Question:
Solution:
Data of the problem:
1) Base 1 measures 8 chains.
2) Base 2 measures 11.8 chains.
3) Width of the Trapezoid is 4.5 chains.
Now, remember that the area of a trapezoid is given by the following formula:
[tex]A\text{ = }\frac{(a+b)}{2}\text{ x h}[/tex]where a and b are the bases and h is the width. Then, replacing the previous data in this equation we obtain:
[tex]A\text{ = }\frac{(8+11.8)}{2}\text{ x (4.5) = }44.55\text{ chains}[/tex]now, 1 chain is equivalent to 0.1 acres, then we have that 44.5 chains are:
[tex]44.5\text{ chains ( }\frac{0.1\text{ acres}}{1\text{ chain}}\text{) = }4.45\text{ acres}[/tex]Then, we can conclude that the correct answer is:
4.45 acres.
