Problema Solution
The length of a rectangle is 3 cm greater than its width. The perimeter is 24 cm. What are the dimensions of the rectangle?
Answer provided by our tutors
let 'x' represent the width, then 'x+3' represents the length
perimeter = 2(l+w), where 'l' is the length and 'w' is the width, so we have:
24 = 2(x+x+3)
solving for 'x' we have x=4.5
4.5+3 = 7.5
the width is 4.5 cm, the length is 7.5 cm
