Answer:
540 ft^2.
Step-by-step explanation:
The area of the trapezoid = h/2 (10 + 18) = 14h.
By Pythagoras the height h = √(5^2 - 4^2) = 3.
So the area of the 2 trapezoidal bases = 2 * 14*3
= 84 ft^2.
Now we calculate the area of the four lateral rectangular sides:
= 10*12 + 18*12 + 2*5*12
= 456 ft^2.
Total area = 456 + 54
= 540 ft^2.
2/3 is bigger than 1/3......TO CHECK this answer 2/3=66% or .66 and 1/3=33% or .33
Therefore, 2/3(66%) is greater than 1/3(33%)
2/3>1/3
5.5 - 1.5 = 4
