Problema Solution
The are of a rectangle is 25x2y4 square feet. The width of the rectangle. is 5xy feet what is the legth of the rectangle?
Answer provided by our tutors
area = length * width
we interpret "25x2y4" to mean "25x^2y^4", where "x^2 = x*x" and "y^4 = y*y*y*y"
let 'l' represent the length of the rectangle, then:
24x^2y^4 = l5xy
l = (24x^2y^4)/(5xy)
l = (24/5)xy^3
the length of the rectangle is (24/5)xy^3 feet
