That’s a trapezoid. To find the area of a trapezoid, you take the 2 bases (9ft and 14ft) and add them up (23ft). Then divide the sum of the 2 bases by 2 (23/2=11.5). Then you take that and multiply it by the height (7ft). So 11.5(7)=80.5ft^2.
Formula for area of trapezoid:
a+b/2•h
a=base 1. b=base 2. h=height

Answer:
After 10 years the investment A will be bigger than investment B.
Step-by-step explanation:
In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.
If after x years the investment A will be equal to investment B, then we can write the equation as

⇒ 50 + 4x = 60 + 3x
⇒ x = 10
Therefore, after 10 years the investment A will be bigger than investment B. (Answer)
