The rectangles below have the same perimeter
6 yd
2 yd
if the area of the brown rectangle is 7 square yards, what are its dimensions?
( yards by
yards

First, let's figure out the perimeter of the first rectangle.  This is equal to 6*2 + 2*2 = 16 yards.

Now, we know that the area of the second rectangle is 7.  There is only one possible combination of numbers that will multiply together to make 7, 7 and 1.  This means that the length is 7 yards and the width is 1 yard.  The dimensions of the rectangle are 7 yards by 1 yard.

We can check this by finding the perimeter of the second rectangle and seeing if it matches the first one.  This is equal to 7*2 + 1*2 = 16, so our answer is correct.
