Arectangle has a width of 4 centimeters and a perimeter of 26 centimeters. find the length.

length = 9 cm

Step-by-step explanation:

perimeter = p =26 cm

width = w=  4 cm

perimeter of a rectangle= 2*w+2*L

L= length

so we have:

26 = 2*(4) +2*L

26= 8 +2L

26-8 = 2L

18 = 2L

L= 18/2

L =9 cm = length

Length would be 9 centimeters.

Step-by-step explanation:

A rectangle has a width of 4 centimeters and a perimeter of 26 centimeters.

Perimeter = 2(Length + Width)

Let the length of the rectangle be 'L'

2(L + 4) = 26

2L + 8 = 26

2L = 26 - 8

2L = 18

L = 18/2

L = 9

Length would be 9 centimeters.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
