Width = x
length = x+10
Area of deck = 144 square feet
Area = length * width
144 = x(x+10)
Solving for x in a quadratic:
x²+10x = 144
x²+10x-144 = 0
Factor:
(x+18)(x-8) = 0
Solving for x:
x = 8, x = -18
Dimensions cannot be negative, therefore x = 8, only.
Length = x + 10
Length = 18
Width = 8

Answer:</h3>
C=52.08π
<h3>
Solution:</h3>
- Circumference of a circle:
- C=2πr
- where
- π=3.14...
- r= radius
- In this case, r is equivalent to 26.04 ft.
- C=2π×26.04
- Multiply:
- C=52.08π (in terms of pi)
