Question

The perimeter of a rectangular box is 120 m. If the breadth of the box is 42 m, ________ is the length of the box. *​

Answer 1

let the length be x m

ATP

• 2( X + 42)=120
• 2x + 82 = 120
• 2x = 120 - 82
• X= (38÷2)
• x=19

the length of rectangle is 19m

Answer 2

Answer:

let the length be x m

ATP

2( X + 42)=120

2x + 82 = 120

2x = 120 - 82

X= (38÷2)

x=19

the length of rectangle is 19m
