Aunit square and a rectangle have the same perimeter. what is the length of the rectangle if its area is 75% of the square's area?

Step-by-step explanation:

Solution:

Denote the length of the rectangle as x.

The perimeter of the unit square (or rectangle) is 4

Make an equation of the area of the rectangle:  (2−x)·x=0.75 ⇒  x2−2x+0.75=0 ⇒ x=0.5, x=1.5

The length will be 1.5 units
