21. the width of a rectangle is four less than one half the length. if the perimeter of the rectangle is 94
meters, find the area of the rectangle.

Good morning ☕️

Area=13×34=442

Step-by-step explanation:

w is the width

p is the perimeter

L is the length

w = L/2 - 4

p=2L+2w

⇔94=2L+2(L/2 - 4)

⇔94=2L+2L-8

⇔102=4L

⇔102/4 = L

⇔ L=34

w = L/2 - 4 = 34/2 - 4 = 17-4 = 13

Area=L×w=34×13=442.

:)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
