Question

A floor is 50 m long and 40 m wide. A square
carpet of sides 30 m is laid on the floor. Find
the area of the floor that is not carpeted?​

Answer 1

Answer: 1100m²

Step-by-step explanation: Area of the floor= l*b

= 50m*40m

= 2000m²

Area of square= s*s

= 30m*30m

= 900m²

Floor that is not carpeted

= 2000m²- 900m²

= 1100m²

Answer 2

Answer:

Area that isn't carpeted is 1,100m²

Step-by-step explanation:

Step 1 : Find the area of the floor :

The floor is rectangular is shape.

Area of the rectangle is given by : l · b

• l (length) = 50m.
• b (breadth) = 40m.

So,

→ Area of the floor = 50 · 40

= 2000m²

Step 2 : Find the area of square carpet :

Each side of the carpet is 30m (given)

→ Area of the carpet : (each side)

= (30)m²

= 900m²

Step 3 : Find the area not carpeted :

Area without carpeted is :

→ Area of the floor - Area of the carpet

→ (2,000 - 900)m²

→ 1,100 m²
