Question

Q14. The perimeter of a square is 320 m

a. Find the side of the square.
b. Find its area.​

Answer 1

Answer:

a. LET THE SIDE BE x

Step-by-step explanation:

a. PERIMETER = 320

4x = 320

x = 320÷4

ie x = 80

So x = side = 80m

b. Area =s×s

=80×80

= 6400 m^

Answer 2

Before finding the answer. Let's find out on how we can find our answer.

• First, to find the side of the square we must divide the perimeter of square with the number of sides.

Perimeter ÷ 4

• Then, multiply side using the formula of

$\sf{Area \: of \: Square } = s \times s$

Given :

Perimeter of Square = 320 m

To find :

• The side of the square.
• Its area

Solution :

Side of Square = 4

= perimeter ÷ 4

= 320 ÷ 4 m

= 80 m

Hence, the side of Square is 80 m.

Area of Square = s × s

= 80 × 80 sq.m

= 6400 sq.m

Hence, the area of the side is 6400 sq.m
