The area of a rectangular prism is found with the formula
2(wl+hl+hw)
where w is width, h is height, and l is length
The area is sqrt 664
No, -Cos(120) is equal to 5, while Cos(-120) is equal to -5.
Hopefully this helps!
Your answer will be 5xplus10
Answer: 52.5 units squared
Step-by-step explanation:
The formula to find the area of a trapezoid is, (base1 + base2)/2 * height
So you find out which variable is which
Base 1 = 4
Base 2 = 3
Height = 15
Then plug it into the formula,
(4+3)/2 * 15
Then solve the order of operations
7/2 * 15
3.5 * 15
52.5 is the answer
