Question

The perimeter of a rectangular field is 100 m. If the field is 20 m wide what is its Length​

Answer 1

30 m

Step-by-step explanation:

Given:-

Perimeter=100

Breadth=20

Perimeter of a Rectangle= 2(L+B)

100m= 2xL+20

$\frac{100 - 20}{2} = length$

Length = 30m

Answer 2

Answer:

length = 30m

Step-by-step explanation:

perimeter of the rectangular field

=> 2×(l+b) = 100

=> l + 20 = 100/2

=> l = 50 - 20

=> l = 30

hope this helps you, have a great day
