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
hope this answer helps you dear...take care
