Answer:
The area of the rectangle is 2820 square inches. The length is 60 inches. The width is 47 inches.
Step-by-step explanation:
Since we know the equation to find the width, we have to set them both to the perimeter of 90 inches. We will use the variable x to represent the length.
x + x - 30 = 90
2x - 30 = 90
You would then subtract 30 from both sides.
2x = 60
Divide by 2 on both sides, finding that the length (x) is 30 inches.
x = 30 inches.
Then, subtract 13 inches from the length to find your width.
60 - 13 = 47 inches
To find your area, you would multiply both of your factors (length and width) together.
60 x 47 = 2,820
And those are your answers!
