2 answers:
Answer:
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.
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
