1725ft^2

Step-by-step explanation:

First, break this up into a rectangle and a triangle.

So, lets make a rectangle. This can be done by taking the lefthand side and turn it into a 30x50 box. This will by itself give you 1500ft^2. But not there just yet!

Next, take the remaining space left and form a right triangle out of it. See how it gives you on the bottom of the trapezoid a length of 65ft but 50 ft have already been used. So, there is 15 ft left to measure.

With this triangle, there's the base (15ft) and for the height, use the 30ft from the rectangle side of the shape.

Now, do (Base * Height) / 2. So, 1(5*30)/2 --> 450/2 ---> 225 ft^2

Lastly, add the rectangle and triangle area together:

1500ft^2 + 225ft^2 = 1725ft^2

Hope that helps.

that is the solution to the question
