Reynaldo cut a triangle out of paper. the lengths of the sides of the triangle are 8 inches,5.5 inches, and 4.5 inches. next, he wants to cut out a rectangle that will have the same perimeter as the triangle. calculate the combined length of the two adjacent sides of a rectangle with the same perimeter.

To find the perimeter of the triangle, we add the lengths of all three sides together:
8 + 5.5 + 4.5 = 18 inches
Since the triangle and rectangle have the same perimeter, the rectangle's perimeter is also 18 inches. To find the dimensions of the rectangle, we need to divide the perimeter by 2 and multiply by 2 because the rectangle has two pairs of equal sides:
Perimeter of rectangle = 18/2 = 9 inches per side
9 x 2 = 18 inches
Therefore, the combined length of the two adjacent sides of the rectangle is 18 inches.
