Question

Find the side of a square. Area= 144 cm, area= 324 cm​

Answer 1

Step-by-step explanation:

Let side of square = a cm

We know that

Area of square = a^2

(i) Area = 144cm

a^2 = 144

a = 12 cm

(ii) Area= 324cm

a^2=324

a = 18cm

Answer 2

Case 1

Area of square=144cm

Side of square=?

We know that,

Side×Side=Area of square

X×X=144

X²=144

X=√144

X=12

Therefore, Side of square=12cm

Case 2

Area of square=324cm

Side of square=?

We know that,

Side×Side=Area of square

X×X=324

X²=324

X=√324

X=18

Therefore,Side of square=18cm
