Question

Find the perimeter of a square whose area is 86.49m².​

Answer 1

Step-by-step explanation:

becouse area of square is L²=86.49

so L is 9.3 m

so the length of square is 9.3 m

so the perimeter =4L

so perimeter =37.2 m

Answer 2

Step-by-step explanation:

Given = area of square = 86.49

We know that,

Area of square =

${a}^{2} = 86.49$

To find = perimeter of square

$a = \sqrt{86.49} = 9.3$

We know that,

Perimeter of square =

$4a \: = 4 \times 9.3 = 37.2 \: m$

Hence the Perimeter of square is 37.2 m
