Question 936089
The length is 7 cm longer than the width, so L = W+7. We'll use the perimeter formula P = 2*(L+W) where the given perimeter is P = 62


P = 2*(L+W)


P = 2*(W+7+W) ... plug in L = W+7


62 = 2*(2W+7) ... plug in P = 62. Solve for W


62 = 4W + 14


62-14 = 4W


48 = 4W


4W = 48


W = 48/4


W = 12


Since W = 12, we can use this to find L


L = W+7


L = 12+7


L = 19


So the length is 19 cm.
