Answer:
93.18 feet
Step-by-step explanation:
Given:
Length of backyard pool = 31.74 feet
Height of backyard pool = 14.85 feet
To find: Length of fencing bought by Mirele
Solution:
To find the length of fencing bought by Mirele, use the formula for the perimeter of a rectangular pool.
Length of fencing bought by Mirele = 2 ( length + height ) = 2 ( 31.74 + 14.85 ) = 2 ( 46.59 ) = 93.18 feet
And aww is I have no idea
Translate that into an equation, and we get:
a+b = 24
a-b = 15
If we add these two equations, we get:
2a = 39
a = 39/2 = 19.5
Plug back in a = 19.5 and solve for b
a + b = 24
19.5 + b = 24
b = 4.5
The two numbers are 19.5 and 4.5.

Step-by-step explanation:
First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:
area rec = 18 * 11
area rec = 198 cm²
small side of tri = 11 - 5
small side of tri = 6 cm
area tri = (height * width) / 2
area tri = (6 * 18) / 2
area tri = 108 / 2
area tri = 54 cm²
area shaded = 198 - 54
area shaded = 144 cm²
