A rectangle's perimeter and area have the same value. The width of the rectangle is 6 units. What is the length of the rectangle

Sliva [168]

Answer:

The length ot rectangle is 3 units.

Step-by-step explanation:

The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :

$perimeter = 2l + 2w$

$area= l \times w$

$perimeter = area$

$2l + 2w = lw$

$let \: w = 6$

$2l + 2(6) = 6l$

$2l + 12 = 6l$

$12 = 6l - 2l$

$4l = 12$

$l = 3 \: units$

A family of 3 shares the minutes on a cell phone plan. Suppose the plan allows for 675 minutes per month. How many minuets are l

Olegator [25]

Let's come up with variables to substitute and make an equation.

T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month

R=T-3P

Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.

R= 675- 3(250)
R= 675- 750
R= -75 minutes

There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.
