Question

A rectangular garden is 30 m broad and 40 m long. Find the length of its diagonal.

Answer 1

Given: Rectangle with breadth = 30 m and length = 40 m.

Step-wise calculation: 

Consider half the rectangle as a right triangle with legs 30 m and 40 m.

d² = 30² + 40² 

= 900 + 1600

= 2500

`d = sqrt(2500)` 

= 50 m

The length of the diagonal is 50 m.
