Question

tke width of a rectangle is 5 cm and its diagonal is 13 cm. What is the perimeter​

Answer 1

34 cm...................

Answer 2

Answer:

34 cm

Step-by-step explanation:

Take width = w

length = l

diagonal = d

by applying Pythagoras theorem

d²=w²+l²

l²=d²-w²

l²=13²-5²

l²=169-25

l²=144

l=12cm

Perimeter=2(l+w)

Perimeter=2(12+5)

Perimeter=2×17cm

Perimeter=34cm
