The perimeter would be 30 feet.
Since the rectangle is 10 ft long and 5 ft wide, you have to all sides together
10 + 10 + 5 + 5 = 30
Triangles are 180 degrees total so 80+40=120, subtract that from 180 and you’ll get B=60
Answer:
The answer is 230 square feet.
Step-by-step explanation:
Find the area of the bases, and the total of it is 280. I then subtracted 50 because the "covers" area is 50. That gives you the surface area without the cover
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
It can't be factored because there are no 2 numbers that when you multiply you get 35 and when you add you get 13.
