Question

A rectangles perimeter and its area have the same numerical value. The width of the rectangle is 3 units. What is the length of the rectangle?

Answer 1

6 units

Explanation:

Given width (breadth) = 3 units

In question,

A rectangle perimeter and area have same value,

putting it in equation...

perimeter of rectangle = area of rectangle

or, 2 ( l+b) = l×b

or, 2 (l+3) = I×3 ( just putting the value of width)

or, 2l+6 =3l

or, 6 = 3l - 2l

Therefore, length (l) = 6 units.
