Question

The length of a rectangle is 4 m longer than its width. If the perimeter of the rectangle is 60 m, find its length and width

Answer 1

Length=17

Width=13

Explanation:

The general formula for calculating the perimeter of a rectangle is 2(l+w)

L=length

W=width

But this value is not given specifically in the question,so we will have to interpret the question

So let solve this

Let the length of the rectangle be x

The width is 4m longer than the length,4+x

So let's solve

2(x+4+x)=60

2(2x+4)=60

4x+8=60

Substrate 8 from both sides

4x=52

Let's make x the subject of formula by dividing both sides by 4

x=13

So the width is 13

Let's calculate the length

4+x

4+13

17

Length=17

Width=13
