To find the perimeter of the square, you add all four sides together: 10x + 10x + (6x + 8) + (6x + 8) 20x + 12x + 16 = P 32x + 16 = P
you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other. 10x = 6x + 8 4x = 8 x = 2
Now you just plug in x and finish the rest of the problem, and you have the answer: 32(2) + 16 = P 64 + 16 = P P = 80
(if you find this helpful, marking this as the brainliest answer would make my day :)
