Question

If one side of a rectangle is three less than the other side and the perimeter is 46 inches, find the area of the rectangle.

Answer 1

Answer:

Area= 70

Step-by-step explanation:

So if one side is unknown we shall call it x.

If the other side is 3 less than the other side then it is x-3.

Now the rectangles sides are: x, x, x-3, x-3

When you add them all up you get the perimeter which will be 4x-6=40

Now the x=10. Now the known sides are 10, 10, 7, 7

7*10 is 70 units squared
