The perimeter of the state of Wyoming is 1280mi. The width is 90mi less than the lenght. Find the width and the length.
I don't know what formula to use or how to write it.
Perimeter = length + length + width + width = 1280 miles
OR P = 2L + 2W = 1280 miles (equation 1)
width + 90 miles = length
OR W + 90 = L (equation 2)
You have two equations and two unknowns. Solve for W and L.
I am trying to work this out and I am not getting anywhere.....help.
he is right
