Answer 2

QUESTION:

perimeter of a square is 60cm. find the side of this square ,then calculate its area.

ANSWER:

We used the formula here;

1.

perimeter of square =

$4 \times side$

2 .

Area of square =

$side \times side$

using the formula;

perimeter of square = 60 cm

$4 \times side = 60cm \\ side = \frac{60}{4} cm \\ side = 15cm$

$\huge\red{side = 15cm}$

now;

$area \: of \: square = 15 \times 15 {cm}^{2} \\ 225 {cm}^{2}$

$\huge\red{area = 225 {cm}^{2}}$
