Step Two State the Givens. AM = 49.5 MN = 71.5 MB = x MP = 97.5
Step Three Set up the Proportion
AM : NM :: x : PM 49.5 : 71.5 :: x : 97.5
Substitute and solve 49.5 / 71.5 = x / 97.5 Cross Multiply 49.5 * 97.5 = 71.5 * x Combine the numbers on the left. 4860.375 = 71.5 * x Divide by 71.5 4860.375 / 71.5 = x x = 67.98
Problem Two Remark This is just a straight application of the Pythagorean Theorem a^2 + b^2 = c^2 a = 10 b = 24 c = ??
Since this is area and you are given the width must divide area by width ( A/W = L) 13.02 divided by 4.2 = 3.1. You can check this by doing 3.1 multiplied by 4.2. It should give you 13.02
