radius=10 ft
Answer:
8
Step-by-step explanation:
8^2=64 8*5=40 64-40=24
Answer:
15cm
Step-by-step explanation:
The formula to calculate the area of a parallelogram is base x height.
Since we know the height and area, we can write the equation:
135 = base x 9
Now we can just divide 9 from both sides to solve for base:
135/9=basex9/9
So we get:
Base = 135/9=15
The length of the base is 15cm.

Diagonal of the square (d):
d = a · √2 = a · 1.414 ( a is a length of a side of the square )
a = 9 : 1.414 = 6.365 inches
Total length:
4 · a + 2 · d = 4 · 6.365 + 2 · 9 = 25.46 + 18 = 43.46 ≈ 43.5 inches.
Answer: A ) 43.5
