3.	The parallel sides of a trapezium are 85 cm and 63 cm and its altitude is 36 cm.Calculate its area. (explain in detail with formula)
Answer» Answer: 2664 cm^2 Step-by-step explanation: Parallel SIDES = 85 cm , 63 cm Altitude = 36 cm Area = h(a + b)/ 2 ( Here 'h' is height, 'a' is ONE of the parallel sides and 'b' is one of the parallel sides) = 36(85+63)/2 = 36(148)/2 = 18*148 = 2664 cm^2

3.

The parallel sides of a trapezium are 85 cm and 63 cm and its altitude is 36 cm.Calculate its area. (explain in detail with formula)

Answer»

Answer:

2664 cm^2

Step-by-step explanation:

Parallel SIDES = 85 cm , 63 cm

Altitude = 36 cm

Area = h(a + b)/ 2 (

Here 'h' is height, 'a' is ONE of the parallel sides and 'b' is one of the parallel sides)

= 36(85+63)/2

= 36(148)/2

= 18*148

= 2664 cm^2

Answer»

ANSWER:

May be the answer of this question is.

By using Pythagoras THEOREM.

H*2=B*2+P*2

PQ*2= QR*2 + PR*2

25*2 = 20*2 + PR*2

625= 400 + PR*2

625-400=PR*2

225=PR*2

PR = underoot 225

PR = 15 cm.

.The number of axes of symmetry in a symmetrical figure is

Answer»

$\huge \sf {\orange {\underline {\pink{\underline {A᭄ɴsᴡᴇʀ࿐ :−}}}}}$

Triangle can have 3, or 1 or no lines of symmetry

Equilateral Triangle(all sides equal,all ANGLES equal)
Isosceles Triangle(two sides equal,two angles equal)
SCALENE Triangle(no sides equal, no angles equal)

Different types of Quadrilaterals (a 4-sided plane shape):

SQUARE(all sides equal,all angles 90°)
Rectangle(opposite sides equal,all angles 90°)
Irregular Quadrilateral has no lines of symmetry

A regular POLYGON has all sides equal, and all angles equal:

An Equilateral Triangle (3 sides) has 3 Lines of Symmetry
Square (4 sides) has 4 Lines of Symmetry
Regular Hexagon (6 sides) has 6 Lines of Symmetry
Regular Heptagon (7 sides) has 7 Lines of Symmetry
Regular Octagon (8 sides) has 8 Lines of Symmetry

A regular polygon of "n" sides has "n" Lines of Symmetry

A line (drawn at any angle) that GOES through its centre is a Line of Symmetry. So a Circle has infinite Lines of Symmetry.
