Problema Solution

The width of jana's rectangular classroom is 1 meter more than 1/4 of the length. If the perimeter if 24 what is the length?

Answer provided by our tutors

Let

x = the length in meters

1 + (1/4)x = the width in meters

P = 24 m the perimeter

Since the perimeter of rectangle equals two times the width plus two times the length we have:

P = 2x + 2(1 + (1/4)x)

Also we know that P = 24 m thus we have the following equation:

2x + 2(1 + (1/4)x) = 24
