Answer 1

Answer:

500

Step-by-step explanation:

0.5m*xm=25m*10m

x m=250/0.5

x m = 250*10/5

x m = 500

Answer 2

Answer:

500 m.

Step-by-step explanation:

Given:

Length of the room floor =  25m

Breadth of the room floor = 10m

Width of the carpet = 50cm

Find:

Carpet required to covered the floor.

Solution :

Area of the room floor = ( l × b )

Area of the room floor = (25 × 10)m²

⇒ (25 × 10)m²

⇒ 250 m²

Width of the carpet = 50cm (0.5 in meter)

Let,

The length of carpet = l

According to question:

Area of floor = Area of the carpet

⇒ 250 = 50 × l

⇒ 250 / 0.5 = l

⇒ l = 500

⇒ l = 500 m.

.°. The answer is 500 m.
