Problema Solution
a rectangle has an area of 24 square units. the width is 5 units less than the length. what is the length in units of the rectangle
Answer provided by our tutors
Let
w = the weight in units, w>0
l = the length in units, l>0
A = 24 square units the area of the rectangle
The width is 5 units less than the length:
w = l - 5
A rectangle has an area of 24 square units:
l*w = 24
plug w = l - 5 into the last equation:
l*(l - 5) = 24
........
........
l = 8 units
The length of the rectangle is 8 units.
