The perimeter and area of the rectangle are 26 and 42, the length of the rectangle is:​

Answer»

Answer:

Check answer.

Step-by-step explanation:

Let the length be a units.

Let the breadth be b units.

Perimeter of rectangle = 2(l+b)

                                26 =2 (a + b)

                              26/2=a+b

                                  13=a+b

                              13-b = a----------(1)

AREA of rectangle= l x b

                    42= a x b-----(2)

PUTTING VALUE of a from eq. (1) in eq. (2) we get,

                     42= (13-b)b

                       42=13b-b²

                     b²-13b +42=0

                 b²-7b- 6b+42=0

                b (b-7) - 6 (b-7)=0

b-7=0  or  b-6=0

b=7   or  b=6

 Therefore, if b=6 then length is 7 units.

If b=7 then length is 6 units.

Te area of triangle ABC in the figure shown here is 52.5 cm². find the area of triangle BDC​

Answer»

ANSWER:

AREA = 1/2bh

52.5cm² = 1/2*B*7.5cm

52.5cm²/7.5cm = 1/2b

7CM = 1/2b

b = 7cm*2

b=14CM

area of ΔBDC = 1/2bh

                           1/2*14cm*4.5cm

62.28 cm² , 10.81cm²

{\mathfrak{\underline{\underline{\blue{Step-By-Step-Explanation:-}}}}}

Step−By−Step−Explanation:−

CASE 1

➭ We know that sides of equilateral Δs are equal.

We will use here formula :-

_________________[Put Values]

Area = √3 * (12)²/4

⇒ Area = √3 * 144 / 4

⇒ Area = 1.73 * 144/4

⇒ Area = 62.28

⇒ Area = 62.28 cm²

\large{\star{\boxed{\boxed{\bf{\purple{Area \: = \: 62.28^{2}}}}}}}⋆

If then prove that tanA = 1/√3​

Answer»

To PROVE :-

  • \sf{tanA=\frac{1}{\sqrt{3}}}

PROOF :-

GIVEN,

\sf{7sin^2A+3cos^2A=4}

_________

\sf{7sin^2A+3cos^2A=4}

:\implies\sf{7sin^2A+3(1-sin^2A)=4}

:\implies\sf{7sin^2A+3-3sin^2A=4}

:\implies\sf{4sin^2A=1}

:\implies\sf{sin^2A=\frac{1}{4}}

:\implies\sf{sinA=\sqrt{\frac{1}{4}}=\frac{1}{2}}

:\implies\sf{sinA=sin30^{\circ}}

:\implies\sf{A=30^{\circ}}

\therefore\sf{tanA=tan30^{\circ}=\frac{1}{\sqrt{3}}}
