Question

The length of a rectangle is 5 cm longer than its width. If the perimeter of the rectangle is 34 cm, what are its dimensions?

Expert Solution
Step 1

Given that the length of a rectangle is 5cm longer than its width and its perimeter is 34 cm.

We know perimeter of the rectangle is  =2×( length + width )

Let , length of the rectangle is l   and width of the rectangle is w. 

Since,   the length of a rectangle (l)  is 5cm longer than its width (w), we can write  l= 5+w
