The perimeter of the rectangle below is 94 units. Find the length of side BC. Write your answer without variables.
D
С
4y
A
5y + 2
B

Step-by-step explanation:

Given,

perimeter = 94

length = 4y

breath = 5y + 2

perimeter = 2 ( l + b )

after inserting values we got,

2 ( l + b ) = 94

2 ( 4y + 5y + 2 ) = 94

2 ( 9y + 2 ) = 94

18y + 4 = 94

18y = 94 - 4 = 90

18y = 90

y = 90/18

y = 5

therefore,

length = 4y = 4×5 = 20
