Question 10456
Start with the formula for the area of a rectangle: 

{{{A = L*W}}}

You are given the area (A = 60 square meters) and the width (W = 6 meters).  You can find the length, L, by substituting the given values for A (60) and W (6) into the formula and solve for the length, L.

{{{60 = L(6)}}} Divide both sides by 6.
{{{10 = L}}}

The length is is 10 meters.
