Question

27. The length and breadth of a rectangle are in the ratio 7:5 and the perimeter is 240m, find the area of

the rectangle​

Answer 1

`Area = 3500`

Explanation:

Given

`Length : Breadth = 7 : 5`

`Perimeter = 240m\\`

Required

Determine the area

The perimeter is:

`Perimeter = 2(Length + Breadth)`

This is then represented as:

`240 = 2(7x + 5x)`

`240 = 2 * 12x`

`240 = 24x`

`10 = x`

`x = 10`

So, the area is:

`Area = Length * Width`

`Area = 7x * 5x`

`Area = 7*10 * 5*10`

`Area = 3500`
