In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.

Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²

Area of the rectangle: 1.5*11 = 16.5 ft²

Total area: 120 + 16.5 = 136.5 ft²

Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³

A window shaped like a parallelogram has an area of 23 4/5 square feet. The height of the window is 2 4/5 feet. How long is the

USPshnik [31]

Answer:

base = 8 $\frac{1}{2}ft$

Step-by-step explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23 $\frac{4}{5}=\frac{119}{5}$

2 $\frac{4}{5}=\frac{14}{5}$

$\frac{119}{5}=\frac{14}{5}h$

Multiply both sides by the reciprocal:

$(\frac{5}{14})(\frac{119}{5})=(\frac{14}{5})(\frac{5}{14})h$

$\frac{119}{14}=h$

$h=8\frac{1}{2}ft$
