The area of the rectangle is 15/64 m2. Find the perimeter of the rectangle if it is 3/8 m wide.

In order to find the perimeter of a rectangle, we need to find its length. We can find the length by dividing the area of the rectangle by its width:
15/64: 3/8 = 15/64 * 8/3 = 120/192 = 15/24 m rectangle width.
We can now find its perimeter. Add the length and width of the rectangle and multiply this amount by 2:
3/8 + 15/24.
Let us bring the fractions to a common denominator. For these terms, it will be 24. The additional factor for the first fraction will be 3:
(3 * 3 + 15) / 24 = (9 + 15) / 24 = 24/24 = 1 m
Answer: the perimeter of the rectangle is 1 m.
