Can you me with both of these and explain and show work on how you do it, this is 6th grade math

To solve this you have to find the area of the rectangle and triangle separate and then you add them to find the whole area of the composite figure.

Rectangle- height is 7 & length is 13 because the triangle’s height is 7 so you subtract 7 from 20. So 7 times 13= 91

Triangle- height is 7 & length is 7
7 times 7 is 49

Then add them which gives you the area of 140

Hope that was a good explanation:))

What are the answer choices?
