Question

88. What is the area of a square whose
perimeter is 64 metres ?
(1) 128 sq. metres
(2) 32 sq. metres
(3)
256 sq. metres
(4) None of the above​

Answer 1

Answer :-

We know that,

Perimeter of a square = 4 × side

Here, we are given perimeter, so by substituting the value, we can find side of the square -

➩ 64 = 4 × s

➩ 4s = 64

➩ s = 64/4

➩ s = 16 m

Now, we have side of the square, and we know that,

Area of square = side × side

Substituting the value in formula -

Area = 16 × 16

= 256 m

Area of square = 256 m²

Answer 2

Given :-

• ★ We know that ★

Perimeter of a square = 4 × side

To find :-

• Here, we are given perimeter, so by substituting the value, we can find side of the square :

Solution :-

→ 64 = 4 × s

→ 4s = 64

→ s = 64/4

→ s = 16 m

Now, we have side of the square, and we know that,

Area of square = side × side

Substituting the value in formula :

Area = 16 × 16

= 256 m²

Hence,

• Area of square is 256 m²
