Question

A carpet of size 5m×2m has 25 cm wide red border.the inner part of the carpet is blue in colour .find the area of blue portion

Answer 1

The area of the blue portion is 32500 sq cm or 3.25 sq m.

Answer 2

Answer:

$6.75 m^2$

Step-by-step explanation:

Length of carpet = 5 m

Breadth of carpet = 2 m

Now we are given that carpet has 25 cm wide red border

Width of border = 25 cm = 0.25 m

So, Length of blue part = 5 m - (0.25+0.25)m = 4.5 m

Breadth of blue part = 2 m -(0.25+0.25)m = 1.5 m

Area of blue part = $Length \times breadth$

                            = $4.5  \times 1.5$

                            = $6.75 m^2$

Hence the area of blue part is $6.75 m^2$
