Question

a)A square-shaped tabletop has a perimeter of 120m. Find its area.​

Answer 1

Answer:

900 m^2

Step-by-step explanation:

Given,

perimeter = 120 m

Therefore, each side = 120/4 m = 30 m

Therefore, area = (30 m)^2 = 900 m^2

Answer 2

Concept

• The perimeter of a square is calculated as the sum of the lengths of its four sides.
• Area of square is the square of its sides

Given

The perimeter of square given is 120cm

Find

We need to find the length of the square

Solution

Given perimeter = 120cm

Therefore Perimeter of square = 4*length

Let the length be x

∴ 4x = 120

∴ x = 30cm

Hence the length is 30cm

As we know square has 4 equal sides = 30cm

So the area of the square = (sides)²

∴ Area of Square = (30)² = 900cm²

Hence the area of square is 900cm²
