The dimensions of a rectangular field are 80m and 18m. Find the length of its diagonal.

Solution:

Given, the dimensions of a rectangular field are 80 m and 18 m.

We have to find the length of the diagonal.

Length of rectangular field = 80 m

Breadth of rectangular field = 18 m

Length of diagonal = √(length² + breadth²)

= √(80² + 18²)

= √(6400 + 324)

= √6724

By using long division to find the square root of 6724,

So, √6724 = 82 m

Therefore, the length of the diagonal is 82 m.
