The figures are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.
Akimi4 [234]

Answer:  Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

\frac{256}{49}=\frac{x}{771}

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

 x=(771)(\frac{256}{49})\\\\x=4,028m^2
