Question

A square has an area of 8100m squared. what is its perimeter?

Answer 1

Answer:

360 m

Step-by-step explanation:

Area of square = 8100m²

Length of one side = √a

= √8100 = 90 m

Perimeter of a square = 4a

= 4 × 90 = 360 m

Answer 2

Answer:

360m

Step-by-step explanation:

area of a square= a² = 8100

side of square = a = √8100 = ±90

since side cant be negative

so a=90

perimeter of a square =4a = 4×90 = 360m
