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%284.5%29%2B2%2810%29 Plug in w=4.5 and L=10


P=9%2B20 Multiply 2%284.5%29 to get 9. Multiply 2%2810%29 to get 20


P=29 Add 9 and 20 to get 29


So the perimeter of the rectangle is 29
