Answer:
This would be true for a rectangle and a square.
Step-by-step explanation:
Rectangles and square have 90 angles. The exterior angles would also equal 90 because 90 + 90 is 180. An interior angle and the exterior angle are supplements (add together to 180).
Because the square has similar lengths, the equation would be
(7x-2)(7x-2)
We can use FOIL to solve this:
The area is 49x^2 - 28x + 4 in^2.
Answer: 22 minutes
