a rectangle has a base of x units,
the perimeter is P=%286x%2B10%29
P=2base%2B2height
2x%2B2height=6x%2B10
2height=6x%2B10-2x
2height=4x%2B10
height=4x%2F2%2B10%2F2
height=2x%2B5

Area of a rectangle is calculated as follows:
A+=+base+%2A+height ...since base=x and height=2x%2B5, we will have
A+=x+%2A+%282x%2B5%29
A+=2x%5E2%2B5x
