Question

) Find the perimeter and area of square of side 30cm. ​

Answer 1

Answer:

square has four equal sides.

So perimeter of a square p=4a

Where a is he length of any one side of the square.

Given p=30cm

⇒4a=30

⇒a= 30/4

=7.5cm

Area of a square A=a^2

⇒A=(7.5)^2

=56.25

Therefore,We get =56.25cm^2
