What is the area of the figure? Answer in decimal form to the nearest hundredth.
sineoko [7]

Answer:

35.75 meters squared

Step-by-step explanation:

The area of a trapezoid is denoted by: A=\frac{(b_1+b_2)*h}{2} , where b_1 and b_2 are the bases and h is the height.

Here, the two bases are 7 1/2 and 5.5 meters and the height is 5.5. So, just plug in the values:

A=\frac{(7\frac{1}{2}+5.5)*5.5 }{2}

7 1/2 is the same as 7.5: A=\frac{(7.5+5.5)*5.5 }{2}=\frac{(13)*5.5}{2} =35.75

Thus, the area is 35.75 meters squared.

Hope this helps!
