Question

Jose is creating a map in the shape of a rectangle whose length is 4 inches longer than its width. Let stand for the width of the map in inches. Write an equation gives the perimeter of the map in terms of ?

Answer 1

P = 4w + 8

Explanation:

Jose is creating a map in the shape of a rectangle whose length is 4 inches longer than its width. Let w stand for the width of the map in inches. Write an equation gives the perimeter of the map in terms of w?

Perimeter of the rectangle = 2(L +w)

L is the length of the rectangle

w is the width

If the length is 4 inches longer than its width, then;

l = w + 4

Substitute into the expression;

P = 2 (L+w)

P = 2(w+4+w)

P = 2 (2w+4)

P = 4w + 8

Hence the perimeter of the map in terms of w is P = 4w + 8
