Question

find the area of a square sheet of paper whoes perimeter bis 60 cm
​

Answer 1

Answer: area= 225 cm^2

Step-by-step explanation:

Perimeter of a square= 4×side

60= 4×side

side=60/4

side= 15 cm

Area of a square= side×side

area=15×15

area= 225 cm^2

Answer 2

Step-by-step explanation:

Question:-

Find the area of a square sheet of paper whose perimeter is 60cm.

Answer:-

Given :-

• The given figure is a square.

• The square sheet of paper has the perimeter of 60cm.

To find :-

Area of the square sheet of paper.

Process :-

Let's find each side of the square using its perimeter.

$∴ Perimeter = 4× a \\ \\ ⇒ 60 = 4×a \\ \\ ⇒4× a = 60 \\ \\ ⇒a = \frac{60}{4} = 15$

Hence,each side of the square sheet of paper is 15cm.

The area of the square:-

$∴ Area = Side × Side \\ \\ ⇒ Area = 15cm \times 15cm \\ \\ ⇒Area = 225 {cm}^{2}$

Hence,the area of the square is 225 cm².

★ More to know

• Perimeter of the square = 4 × side

• Area of the square = Side × Side

Other rectilinear figures:-

• Area of rectangle = Length × Breadth

• Perimeter of rectangle = 2 × ( L + B )
