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

$2x - 9 = 11$

Answer 2

Answer:

$6.75 m^2$

Step-by-step explanation:

Given : Length of carpet = 5 m

            Breadth of carpet = 2 m

             Carpet has 25 cm wide red border  

To Find : the area of blue portion

Solution

Length of carpet = 5 m

Breadth of carpet = 2 m

We are given that carpet has 25 cm wide red border  

So,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 portion is $6.75 m^2$
