Question

PERIMETER=30cm
FIND THE EACH SIDE OF SQUARE WITH DEFINATION

Answer 1

Answer:

We know

Square is a 4 sides figure with 4 equal sides and all angles are 90° each

also

we know

Perimeter of a Square= 4s(4×side)

that is

Let the length a of a single side be x

therefore the equation is

$4 \times x = 30 \\ x = \frac{30}{4} \\ x = 7.5$

therefore length of each side is 7.5cm

Let's check whether it's correct or not

that is

$4 \times 7.5 = 30 \\ 30 = 30$

L.H.S=R.H.S

hence verified
