Question 922962
 1. A triangle has an area of 5 square inches and a base of 2x. What is the height of the triangle in terms of x?
We know that the area of a triangle: A = {{{1/2}}}b*h
In this problem A = 5, b = 2x, therefore
{{{1/2}}}(2x)*h = 5
get rid of the fraction, multiply both sides by 2
(2x)*h = 10
Divide both sides by 2x
h = {{{10/(2x)}}}
Reduce the fraction, 2 cancels into 10, we are left with
h = {{{5/x}}}

  2. A rectangle has an area of 70 square inches and a width of 3.5w.
 What is the the length of the rectangle in terms of w?
we know that A = L * W
In this problem A = 70 and W = 3.5w, therefore
L * 3.5w = 70
Divide both sides by 3.5w, leaving us with:
L = {{{70/(3.5w)}}}
Reduce the fraction, 3.5 goes into 70 twenty times
L = {{{20/w}}}
