Answer:
530 in ^2
Step-by-step explanation:
The figure given is a triangle
We use the formula for the area of a triangle
A = 1/2 bh where b is the length of the base and h is the height
The height is perpendicular to the base( at 90 degrees)
A = 1/2 ( 26.5) * ( 40)
= 530 in ^2
Answer: x=5
Step-by-step explanation:
5 x 5 = 25 - 7 = 18
so x=5
Answer: X=-37
Step-by-step explanation:
Total surface area of a triangular prism = width x height +(sum of sides + width) x length
475 = (width x 10) + (5 + 5 + width) x 15
475 = (10 x width) + (10 + width) x 15
475 = (10 x width) + 150 + (15 x width)
475 - 150 = 25 x width
325 = 25 x width
width = 325/25 = 13 feet
