Answer:
D. w = l − 40; the width increases as the length decreases
Step-by-step explanation:
The formula for the perimeter of a rectangle =
P = 2l + 2w
Where to find the Width, we make w the subject of the formula.
Hence:
P - 2l = 2w
w = P - 2l/2
From the question, P = 80
Hence,
w = 80 - 2l/2
w = 80/2 - 2l/2
w = 40 - l
The width of a rectangle is always the longer side ,hence:
D. w = l − 40; the width increases as the length decreases
Three fractions that are generated than 1/2 but less than one are 3/4, 4/5, 8/9
