Question

The length of a rectangle is 5m greater than its breadth , and its perimeter is 250m . Find the length and breadth of the rectangle .
​

Answer 1

Respuesta:

40 meters

Explicación paso a paso:

Let x be the width of the rectangle, then the length of it is x + 5.

As the perimeter is 150, we can set up an equation using this fact:

2x + 2(x + 5) = 150

Solving for x, we obtain:

2x + 2x + 10 = 150

4x + 10 = 150

4x = 140

x = 35

so the width and length are 35 and (35 + 5 =)40 meters.
