The length of a rectangle is three times its width. if the perimeter is at most 112 centimeters, what is its greatest possible value for width?

width = 14 , length = 42

Step-by-step explanation:

Here we have to find the width of the rectangle using the fact that length is 3 times the width and perimeter is given

Let the length of the rectangle = x

Hence the width of the rectangle = 3 x

The formula for the perimeter is

P=2(l+b)

Given P = 112

Hence

112=2(l+b)

l+b=56

substituting values of l and b in this

x+3x= 56

4x=56

x=14

Hence width = 14 cms

length = 3*14 = 42 cms

the answer is d. 75%

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
