Answer:
43.5√3 sq. units
Step-by-step explanation:
Base 1 of trapezoid is 10.
Base 2 of trapezoid is 16 + 3 = 19
The height = 3√3 (To get the height you had to multiply the number 3 from the bottom base of the trapezoid by the square root of three)
Now plug these numbers into the trapezoid formula: A = 1/2(3√3)(10 + 19)
Simplify to get: 43.5√3 sq. units
Hope this helps you understand!
To minimize the cost, you would want the side with the brick wall to be as small as possible. as you provided no restraints to the size, a garden which is 1 foot wide by 22 feet long would be most cost effective, with 22 feet times 2 sides equaling 44 feet in total, plus one foot for the back wall. With a total of 45 feet of fence costing $450, and 1 foot of brick which will cost $20, the total cost would be $470.
