Answer:
26.25 square feet
Step-by-step explanation:
Calculation to determine the area of the seat
Using this formula
Area=1/2*(b1+b2)*h
Where,
b1=8 feet
b2=7 feet
h=3.5 feet
Let plug in the formula
Area=1/2*(8+7)*3.5
Area=1/2*15*3.5
Area=26.25
Therefore the area of the seat is 26.25 square feet
No, surface area and total surface area are the same.
-3b=-9. Plug in 3. -3(3)=-9.
63
5 tens equals 50
13 ones equals 13
50 +13 = 63
