Solved by pluggable solver: Perimeter of a Rectangle


P=2w%2B2L Start with the general perimeter formula where W is the width and L is the length of the rectangle


P=2%2820%29%2B2%2818%29 Plug in w=20 and L=18


P=40%2B36 Multiply 2%2820%29 to get 40. Multiply 2%2818%29 to get 36


P=76 Add 40 and 36 to get 76


So the perimeter of the rectangle is 76
