Question

The perimeter of a rectangle is 80x. The base is 7 times the height. In terms of x, what are the dimensions of the rectangle. What is the area?

Thanks..

Answer 1

call the height h
then the base is 7h
the perimeter is 80 x
so
2 h + 14 h = 80 x
16 h = 80 x
h = 5 x
area = h (7h) so put in 5x for h and you have it
