Find the length of a diagonal of a rectangle with dimensions 20m by 15m

Solution:

Given, the dimensions of a rectangle is 20 m by 15 m.

We have to find the length of a diagonal of a rectangle.

We know, Diagonal² = Length² + Breadth²

Length of a rectangle = 20 m

Breadth of a rectangle = 15 m

Diagonal² = (20)² + (15)²

Diagonal² = 400 + 225

Diagonal² = 625

Taking square root,

Diagonal = √625

Diagonal = 25 m

Therefore, the length of a diagonal of a rectangle is 25 m.
