Question

The perimeter of a rectangle is 320cm. If the breadth = 120 cm, then find the length of the rectangle ​

Answer 1

Solution:

=> Perimeter = (Length × Breadth)

=> Length = 320/120

=> Length = 8/3

=> Length = 2.67 cm

Answer 2

Answer:

length of rectangle is equal to 40 cm

Step-by-step explanation:

let length of rectangle be x

perimeter of rectangle=2(l+b)=320

so 2(x+120)=320

2x+240=320

2x=320-240

2x=80

x=80/2=40

therefore x=40 cm
