ong>Answer:

In area of a trapezium we will discuss about the formula and the solved examples in area of a trapezium.

Trapezium:

A trapezium is a quadrilateral having one pair of parallel opposite sides. In the given figure, ABCD is a trapezium in which AB ∥ DC.

Area of a Trapezium:

Let ABCD be a trapezium in which AB ∥ DC, CE ⊥ AB, DF ⊥ AB and CE = DF = h.  

Prove that:

Area of a trapezium ABCD = {¹/₂ × (AB + DC) × h} square units.

Proof:     Area of a trapezium ABCD

           = area (∆DFA) + area (rectangle DFEC) + area (∆CEB)

           = (¹/₂ × AF × DF) + (FE × DF) + (¹/₂ × EB × CE)

          = (¹/₂ × AF × h) + (FE × h) + (¹/₂ × EB × h)

           = ¹/₂ × h × (AF + 2FE + EB)

           = ¹/₂ × h × (AF + FE + EB + FE)

           = ¹/₂ × h × (AB + FE)

           = ¹/₂ × h × (AB + DC) square units.

           = ¹/₂ × (sum of parallel sides) × (distance between them)

Formula of Area of a trapezium = ¹/₂ × (sum of parallel sides) × (distance between them)

Solved Examples of Area of a Trapezium

1. Two parallel sides of a trapezium are of lengths 27 cm and 19 cm respectively, and the distance between them is 14 cm. Find the area of the trapezium.

Solution:  

Area of the trapezium

     = ¹/₂ × (sum of parallel sides) × (distance between them)  

     = {¹/₂ × (27 + 19) × 14} cm²

     = 322 cm²

2. The area of a trapezium is 352 cm² and the distance between its parallel sides is 16 cm. If one of the parallel sides is of LENGTH 25 cm, find the length of the other.

Solution:  

Let the length of the required side be x cm.  

Then, area of the trapezium = {¹/₂ × (25 + x) × 16} cm²  

                                             = (200 + 8x) cm².  

But, the area of the trapezium = 352 cm² (given)  

Therefore, 200 + 8x = 352  

               ⇒ 8x = (352 - 200)  

               ⇒ 8x = 152  

               ⇒ x = (152/8)  

               ⇒ x = 19.  

Hence, the length of the other side is 19 cm.  

3. The parallel sides of a trapezium are 25 cm and 13 cm; its nonparallel sides are equal, each being 10 cm. Find the area of the trapezium.

Solution:

Let ABCD be the given trapezium in which AB = 25 cm, DC = 13 cm, BC = 10 cm and AD = 10 cm.

Through C, draw CE ∥ AD, MEETING AB at E.

Also, draw CF ⊥ AB.

Now, EB = (AB - AE) = (AB - DC)

             = (25 - 13) cm = 12 cm;

       CE = AD = 10 cm; AE = DC = 13 cm.

Now, in ∆EBC, we have CE = BC = 10 cm.

So, it is an isosceles triangle.

Also, CF ⊥ AB

So, F is the midpoint of EB.

Therefore, EF = ¹/₂ × EB = 6cm.

Thus, in right-angled ∆CFE, we have CE = 10 cm, EF = 6 cm.

By Pythagoras’ theorem, we have

CF = [√CE² - EF²]

    = √(10² - 6²)

    = √64

    = √(8 × 8)

    = 8 cm.

Thus, the distance between the parallel sides is 8 cm.

Area of trapezium ABCD = ¹/₂ × (sum of parallel sides) × (distance between them)

                                       = {¹/₂ × (25 + 13) × 8 cm²

                                       = 152 cm²

4. ABCD is a trapezium in which AB ∥ DC, AB = 78 cm, CD = 52 cm, AD = 28 cm and BC = 30 cm. Find the area of the trapezium.

Solution:

Draw CE ∥ AD and CF ⊥ AB.

Now, EB = (AB - AE) = (AB - DC) = (78 - 52) cm = 26 cm,

CE = AD = 28 cm and BC = 30 cm.

Now, in ∆CEB, we have

S = ¹/₂ (28 + 26 + 30) cm = 42 cm.

(s - a) = (42 - 28) cm = 14 cm,

(s - b) = (42 - 26) cm = 16 cm, and

(s - c) = (42 - 30) cm = 12 cm.

area of ∆CEB = √{s(s - a)(s - b)(s - c)}

                     = √(42 × 14 × 16 × 12) cm²

                     = 336 cm²

Also, area of ∆CEB = ¹/₂ × EB × CF

                              = (¹/₂ × 26 × CF) cm²

                              = (13 × CF) cm²

Therefore, 13 × CF = 336

⇒ CF = 336/13 cm

Area of a trapezium ABCD

                   = {¹/₂ × (AB + CD) × CF} square units

                   = {¹/₂ × (78 + 52) × ³³⁶/₁₃} cm²

                   = 1680 cm²

ong>Answer:

side and angle

Step-by-step explanation:

1. SAS (Side-Angle-Side): If two pairs of sides of two triangles are equal in length, and the INCLUDED ANGLES are equal in MEASUREMENT, then the triangles are congruent.

2. SSS (Side-Side-Side): If three pairs of sides of two triangles are equal in length, then the triangles are congruen

value of X is 6*5 =30

thus the ANSWER is 30

C=2πr

d=2r

Solving forC

C=πd=π·14≈43.9823cm

C≈43.98cm

If P = 7, Q= 4, then 7+4 = 11 (SATISFIES 2nd EQ)

and

74 – 47 = 27 ( it satisfies 2nd eq as well)

Therfore the values of P & Q are 7 and 4 RESPECTIVELY..
