Question

find the length of the diagonal of a rectraingle whose sides are 15 cm and 8cm

Answer 1

l=15cm and b=8cm

d²=l²+b²

d²=15²+8²

d²=225+64

d²=289

d=√289

d=17

Hence ,Diagonal of rectangle is 17cm

Answer 2

Given

Length = 15 cm , Breadth = 8cm .

Length of the rectangle is AB = 15cm.

Breadth of the rectangle is BC = 8 cm

finding the diagonal using Pythagoras theorem

CD^2 = AB^2 + BC^2

CD^2 = 15^2 + 8^2

CD^2 = 225 + 64

CD^2 = 289

CD = √289

CD = 17.
