Question

8. How many metres of carpet 50 cm wide will be required to cover a floor 25 m long and 10 m wide?​

Answer 1

Answer:

Area of carpet = area of the floor of the room

= 25 × 10 sq.m

= 250 sq.m

Width of the carpet = 50cm = 0.5 m

So , Length of the carpet =

$= \frac{ area}{width}$

$= \frac{250}{0.5}$

= 500 metres

I hope it helps u dear friend ^_^♡♡

Answer 2

Given :-

Length of the floor =  25 m

Breadth of the floor = 10 m

Width of the carpet = 50 cm

To Find :-

Carpet required to covered the floor.

Analysis :-

First find the area of the floor by substituting the values in it's respective formula.

Then convert the width to meters.

Area of floor = Area of the carpet

Consider length to be a variable and find it accordingly.

Solution :-

We know that,

• l = Length
• b = Breadth
• w = Width

By the formula,

$\underline{\boxed{\sf Area \ of \ rectangle=Length \times Breadth}}$

Given that.

Length (l) = 25 m

Breadth (b) = 10 m

Substituting their values,

Area = 25 × 10

Area = 250 m²

Given, Width of the carpet = 50 cm

By converting,

1 cm = 0.1 m

50 cm = 0.50 m

Let us consider the length to be 'x'.

According to the question,

Area of floor = Area of the carpet

250 = 0.5 × x

By transposing,

x = 0.5/50

x = 500

Therefore, 500 m of carpet are required to cover the floor.
