Question

The area of a square is 144 sq cm. What is the perimeter?​

Answer 1

Area of square = 144

Also

Area of square = Side²

So,

Side²=144cm

Side = √144

√144= 12

So side=12cm

Perimeter of square = ${Side{\times{4}}}$

Perimeter of square = ${12{\times{4\:=\:48}}}$

Perimeter of square = 48 cm

Answer 2

Answer:

$\huge{\purple{❥}\pink{a}\orange{n}\blue{s}\red{w}\green{e}\purple{r}}$

area of square = side × side

144 = side x side

side = root 144

side =12cm

perimeter = 4×side

perimeter =4×12

perimeter =48

hope this helps
