Question

A plain carpet 10m long and 6.5m wide has a border of width 75cm a long each of it is sides find the total area of the border

Answer 1

first we take out the carpet area

the formula = l×b =10×6•5=65

then after widht = 65m×7•5cm

=487•5

Answer 2

Answer:

Answer:-

Given:

Length of a carpet = 10 m

Width of the carpet = 6.5 m

And , boarder of this carpet has a width of 75 cm = 75/100 = 7.5 m. [ ∵ 1 cm = 1/100 m ]

We have to find the area of the path.

We can say that,

Area of the carpet (with border) - Area of the carpet = Area of the border.

As , length > breadth ; the carpet is in a rectangular shape.

We know that,

Area of a rectangle = length * breadth

So,

⟶ (10 + 7.5)(6.5 + 7.5) - (10)(6.5) = Area of the border

⟶ (17.5)(14) - 65 = Area of the border

⟶ 245 - 65 = Area of the border

⟶ 180 m² = Area of the border
