Question

What is the perimeter of the square if the area is 100 sq.cm?

Answer 1

Answer:

40 cm

Step-by-step explanation:

Given :

Area of the square = 100 cm²

We know :

Area of the square = side²

100 = side²

side = ± 10 cm

Since side cannot be in negative.

Side of square = 10 cm

Perimeter of the square = 4 × side

Perimeter of the square = 4 × 10 cm

Perimeter of the square = 40 cm

Therefore , perimeter of the square is 40 cm.

Answer 2

$area \: of \: square = side {}^{2}$

$100 = side {}^{2}$

10= side

perimeter of square =4×side

4×10

=40

perimeter of square is 40
