Question

in the given llam, PORS, OR is 3cm. greater than PQ, iFts perimeter is 70cm
find PQ and QR

​

Answer 1

ANSWER:

Given - QR =3 cm,

perimeter = 70cm

QR = PS =30 cm (opposite sides are equal)

suppose PQ = x

PQ = RS =x

perimeter = sum of all sides

70 = PQ + QR + RS + PS

70 = x + 3 + x + 3

70 = 6 + 2x

70 - 6 =2x

64 = 2x

64 ÷ 2 = x

32 = x

x = 32
