In the diagram below, PQRS is a parallelogram with a perimeter of 26 and an area of 28. What is the perimeter of rectangle OSTQ? Include an explanation of how you solved the problem.

1 answer

The perimeter of rectangle OSTQ can be found by adding the lengths of the sides of the rectangle together. The length of side OQ is the same as the length of side RS, which is 8. The length of side ST is the same as the length of side PQ, which is 6. Therefore, the perimeter of rectangle OSTQ is 8 + 8 + 6 + 6 = 28.
