Question

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

Answer 1

Answer:

$Area = 3500$

Step-by-step 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:

$Area = Length * Width$

$Area = 7x * 5x$

$Area = 7*10 * 5*10$

$Area = 3500$
