The length of a rectangle is (x + 3) ft and the width is x ft. Write an expression in simplest form that represents the perimeter of the rectangle.

Question

How would i solve this and what's the answer?

Answer 1

Perimeter is the distance around the rectangle

Perimeter = Length + Length + Width + Width

= (x + 3) + (x +3) + (x) + (x)

Grouping like terms

= (x + x + x + x + 3 + 3)

= 4x + 6
