Question

Hi
please solve the question fast by Pythagoras theorem of a triangle​

Answer 1

Step-by-step explanation:

we have to take a imaginary line from p then a right triangle is formed and a rectangle is formed

OR = PA = 12cm

PQ = 5cm by OP - RA

we have:

perpendicular = 5cm

base = 12cm

hypotenuse = ?

by Pythagoras theorem,

h^2 = p^2 + b^2

h^2 = 5cm^2 + 12cm^2

h^2 = 25cm + 144cm

h^2 = 169cm

h = root 169cm

h = 13cm

now, we have all side of trapezium then perimeter = OR + OP + RQ + QP

= 12cm + 10cm + 15cm +13cm

= 50cm ans
