Question

rita has bought a carpet of size 4m ×20/3m but her room size is 10/3m ×16/3m .what fraction of area should be cut off to fit wall to wall carpet into the room

Answer 1

Given:

Rita has bought a carpet of size 4 m × (20/3) m

Her room size is (10/3) m × (16/3) m

To find:

The fraction of area that should be cut off to fit wall to wall carpet into the room

Solution:

Formula to used:

Area of rectangle = length × breadth

Using the formula, we have

The area of the carpet that Rita had bought = [4 × $\frac{20}{3}$ ] m² = $\frac{80}{3}\: m^2$

and

The area her room = [$\frac{10}{3}$ × $\frac{16}{3}$] m² = $\frac{160}{9}\:m^2$

Now,

The fraction of area of the carpet that should be cut off is,

= [Area of the carpet ] - [Area of the room]

= $\frac{80}{3}\: m^2$ - $\frac{160}{9}\:m^2$

= $\frac{240\:-\:160}{9} \:m^2$

= $\bold{\frac{80}{9}\:m^2}$

Thus, $\frac{80}{9}\:m^2$ of area should be cut off from the carpet to fit wall to wall into the room.
