Answer:
180 Square Feet
Step-by-step explanation:
For Rectangle:
l = 9 ft
b = 20 ft
Area of Rectangle
![= l \times b \\ = 9 \times 20 \\ = 180 \:square \: feet](https://tex.z-dn.net/?f=%20%3D%20l%20%5Ctimes%20b%20%5C%5C%20%20%3D%209%20%5Ctimes%2020%20%5C%5C%20%20%3D%20180%20%5C%3Asquare%20%5C%3A%20%20feet)
Answer:
b
Step-by-step explanation:
This problem is currently unsolvable as we do not know if the semi-circle has a radius of 31 or 19.
Answer:
b=8
Step-by-step explanation:
This is a right triangle, as we can see from the box in the corner.
We can use Pythagorean theorem to find the unknown side
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
15^2 +b^2 = 17^2
225 + b^2 =289
Subtract 225 from each side
225-225 + b^2 = 289-225
b^2 =64
Take the square root of each side
sqrt(b^2) = sqrt(64)
b = 8
