Question

A square has an area of 196 square inches. What is the premeter of the square.

Answer 1

56 inches

Explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 196 , then

s² = 196 ( take square root of both sides )

s =
`√(196)` = 14

The perimeter is the sum of the 4 congruent sides , so

perimeter = 4 × 14 = 56 inches
