The length of a rectangle is 11 units more than its width. The perimeter of the rectangle is 182 units. Solve for the dimensions
alekssr [168]

Answer:

2160 units square

Step-by-step explanation:

We are given the perimeter of 182 units and that the lengths are 11 more units than the width. So the length is W+11, eleven more than the width. There is also 2 width sides so the sum of the lengths are 2W+22. There is also 2 width sides so if you add that to the equation the perimeter equals 4W+22.

4W+22=182

4W=160

W=40

So the width is 40 units, and the length is 11 more so the length is 54 units. Multiply these two numbers to get the area. 44*54=2160 square units.
