The width, you already know is 10yd. And the area is 672yd.^2, so 672/10 is 67.2
The length is 67.2yd.
Answer:
x=27
y=9√3
Step-by-step explanation:
Since the angles in a triangle add up to 180, and we know that one angle is 30 and the other 90, the last angle is (180-90-30)=60°. Then, we can identify this as a 30-60-90 triangle, so the side opposite the 90 degree angle is a value of 2a, the side opposite the 30 degree one a, and the side opposite the 60 degree one a√3. We know 2a to be 18√3, so y, the side opposite the 30 degree angle, is a (18√3/2=9√3) and x, the side opposite the 60 degree angle, is a√3, or 9√3*√3=9*3=27
Answer:
30.96 m^2
Step-by-step explanation:
Side length of the square is also the diameter of the semicircle so:
r = 0.5 * 12 m = 6 m
Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:
Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area
(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)
= 144 - 56.52 - 56.52
= 30.96 m^2
Answer:
192 square feet
Step-by-step explanation:
find the are of each room.
4 times 12 is 168
8 times 3 is 24
add both of those together and get 192
i can attach a picture if you want me to
Multiply 190 by 0.27 and you should get your answer
