An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.
The formula for the area of a triangle is A=1/2*b*h
A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3
Hope this helps

First, we need to find the area of the two rectangles in this picture. We know that area = l*w.
So for the larger rectangle, we know the l = 100 m, and the w = 60 m. Let us find the area:

So the larger rectangle area is 6000 m.
The smaller rectangle has dimensions that are 2 m less on every side. So we can recalculate these dimensions as l = 96 m and w = 56 m.
Let's find the area of the smaller rectangle:

So we know that the area of the smaller rectangle is 5,376 m.
The area of the jogging path is going to be the difference between these two rectangles. Let us solve:

So now we know that
the area of the jogging path is
