the length of a rectangle is 5 cm more than its width. the perimeter is five times the width. what are the dimensions of the rectangle
Answer provided by our tutors
Let
l = the length of the rectangle
w = the width of the rectangle
The length of a rectangle is 5 cm more than the width:
l = 5 + w
The perimeter is 5 times the width:
2(l + w) = 5w
We have the following system of equations:
l = 5 + w
2(l + w) = 5w

........
l = 15 cm
w = 10 cm
The dimensions of the rectangle are: the length is 15 cm and the width is 10 cm.
