A rectangle has an area of 69.6m^2.
omeli [17]

Answer: The perimeter of the rectangle is 53.8. One side is 24, and the other is 2.9.

Step-by-step explanation:

First you need to divide 69.6 meters by 2.9. This gives you 24 as the other side of the rectangle(remember that the area of a rectangle is lw). Next you multiply 2.9 x 2. This gives you 5.8, then you multiply 24 by 2. This gives you 48. You add the two values together,and you get the perimeter of the rectangle as 53.8.
