Question

The perimeter and the area of a rectangle have the same value. The wdth of a rectangle is 7cm. What is the length of the rectangle?

Answer 1

Explanation:

Given that the perimeter and the area are the same:

P=A

2×(L+7)=L×7

Solving for L:

2L+14=7L

14=5L

L=14/5=2.8 cm

So, the length of the rectangle is 2.8cm.
