Well, the idea being, that 1 is the 100% unit, so say 0.5 is 50% and so on.
so, let's convert 7 and 7/8 from mixed to improper first.
Answer:
the correct answer is (5x+2)^2
The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:

x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.
s = 2π(3.5)(1/2) ≈ 11.00
Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.
Answer:f (x) = a(x - h)2 + k, where (h, k)
