Question

For the rectangle provided, the length of this rectangle is 5 mm longer than its width. The perimeter of this rectangle is more than 42 mm. Let w equal the width of the rectangle.
A) Define the length of the rectangle in terms of w (the width).

B) Use the expressions to write an inequality based on the given information.

C) Solve the inequality, clearly indicating the width of the rectangle.

Answer 1

A) length= w+5
width=w
perimeter=42mm
B) 2(w+5)+2w>42
2w+10+2w>42
4w>32
w>8
The width should be greater than 8 and the length should be more than 13.

Hope this helps!
