Answer:
Step-by-step explanation:
So u need to find the circumference of the half circle by finding the circumference of the whole circle and dividing by 2 so that gives you 12.565 then u find the perimeter of the rectangle but not the 4th side cause that’s on the inside when u do that u get 10+10+8 which is 28 then add the half circle and I get 40.565 ft but round to nearest hundred so 40.56 ft
2 * 2 and 3/4.
2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4
2 * 11/4 = 22 / 4 = 5 and 2/4
= 5 and 2/4 or 5 and 1/2 or 5.5
Hope this helps.
