Answer:

330

Step-by-step explanation:

Hello There!

The shown figure is a trapezoid with the following dimensions:

Height - 11m

Base 1 - 41m

Base 2 - 19m

Given this information we need to find the area

Remember the formula for the area of a trapezoid is

A=\frac{a+b}{2} h

where a and b are bases and h is the height

Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula

So...

A=\frac{19+41}{2} 11\\19+41=60\\\frac{60}{2} =30\\30*11=330\\A=330

In conclusion the area of the figure is 330 square units
