Question

MATH PLEASE HELP!

A square field has an area of 479² ft What is the approximate length of a side of the field? Give your answer to the nearest foot. Explain your response.

Answer 1

A = 479 sq ft

479 = x²

square root of 479 = square root of x²

21.89 = x

rounded= 22 ft

Answer 2

≈ 22 ft

Explanation:

The area (A) of a square is calculated as

A = s² ( where s is the side length )

Given A = 479, then

s² = 479 ( take the square root of both sides )

s =
`√(479)` ≈ 22 ft ( to the nearest foot )
