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

Jobisdone [24]

Answer:

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
