Please help, easy geometry​

Mathematics
1 answer:
tester [92]3 years ago
8 0

Answer:

Step-by-step explanation:

There are a few ways to go about doing this problem. One method would to divide the shape into two triangles and a rectangle and then find the area of those shapes and then add them all up. I am not going to do that because that is the long way to solve this problem.

<u>With that said, you can use the trapezoid formula</u>

A = h*\frac{b1 + b2}{2}

b1 = 3

b2 = 11

h = 9

<u>Plugin the data into our model and do the math.</u>

A = h*\frac{b1 + b2}{2}

A = 9*\frac{3 + 11}{2}

A = 9*\frac{14}{2}

A = 9 * 7

A = 63 \ yd^2
