Answer:
<h2>510.4 ft²</h2>
Step-by-step explanation:
We have:
two trapezoids with bases 15ft and 7ft and height 5ft.
four rectangles 5ft × 11ft, 15ft × 11ft, 9.4ft × 11ft and 7ft × 11ft.
The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
Substitute:

The formula of an area of a rectangle:

l - length
w - width
The dimensions of rectangle l × w
Subtitute:

The surface area of the figure:
[tex]S.A.=2A_t+A_1+A_2+A_3+A_4\\\\S.A.=2(55)+55+165+103.4+77=510.4\ ft^2[/text]
Answer:
129.25
Step-by-step explanation:
Area of the rectangle
Area = L * W
L = 10
W = 9
Area = 9 * 10 = 90
Area of the1/2 circle
Area of a whole circle = pi * r^2
Area of a 1/2 circle = pi * r^2 /2
d = 10
r = d/2
r = 10/2
r = 5
Area of the 1/2 circle = 3.14 * 5^2 /2 = <u> 39.25</u>
Total 129.25
4 ft because the area of the bathroom floor is 24 sq ft and the width of the bathroom is 6 ft then the answer is 4 ft. 6 x 4 = 24
