Question

find the
length of a
diagonal of a rectangle
with dimension 20m and
15 m.​

Answer 1

Solutions :-

We have,

Length = 20 cm

Breadth = 15 cm

Let the Diagonal of rectangle be x

Find the length of Diagonal of a rectangle :-

(Diagonal)² = (Length)² + (Breadth)²

=> x² = (20)² + (15)²

=> x² = 400 + 225

=> x² = 625

=> x = √625 = 25

Hence,

Length of Diagonal of rectangle is 25 cm

Answer 2

By pythagoras theorem,

H²=P²+B²

H²=20²+15²

H²=400+225

H=√625

H=25cm
