The area of a triangle is given by
where
b is the length of the base
h is the height
For triangle ABE, we know that
A = 40 (area)
h = 8 (height)
So we can find the length of the base AE:
Now we observe that the base of the rectangle, AD, is the sum of AE and DE, therefore:
We also know the height of the rectangle AB is 8, and that the area of a rectangle is
where b is the base and h the height. Therefore, the area of this rectangle is

The dimensions of the frame are 15 in x 13 in
Step-by-step explanation:
Let
x ----> the length of the picture
y ----> the width of the picture
we know that
-----> equation A
The area of the picture, including the frame is
so
----> equation B
substitute equation A in equation B
solve for y
solve the quadratic equation by graphing
The solution is y=7 in
