Question

The perimeter of a rectangle field is 18 cm: its breadth is 2cm find the length of the field

Answer 1

Step-by-step explanation:

Perimeter of a rectangle = 2(l+b)

18cm = 2(l+2)

18 ÷2 = l+2

9= l+2

9-2 =l

7 =l

length of field is 7cm

Answer 2

★ Given:-

‏‏‎ ‎

• ➪ Perimeter of a rectangle field is 18cm.

• ➳ Perimeter of a rectangle = 2 ( l + B )

‏‏‎ ‎

• ➳ 18 cm = 2 ( l + 2 )

‏‏‎ ‎

• ➳ 18/2 = l + 2

‏‏‎ ‎

• ➳ 9 = l + 2

‏‏‎ ‎

• ➳ 9 - 2 = l

‏‏‎ ‎
