Question

What is the length, in feet, of the diagonal of a square with 8-foot sides? Round to the nearest tenth.

Answer 1

11 feet

Explanation:

Length of diagonal of square of side a = √2a

Here value of a = 8 feet

Therefore length of diagonal d = √2×8 = 1.414×8 = 11.312 feet

So after rounding to the nearest tenth the length of diagonal becomes 11 feet
