Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
The answer is 560 because if say you had to round 567 to the nearest ten, that would be 570 because the nearest 10 to 67 is 70, but here you have 563 so the nearest 10 to 63 is 60 :)
