Question

a farmer wants to fence a rectangular field measuring 40m by 10m one of whose length is along the boundary wall of his house .The required length of fence is ?

Answer 1

The is 100m

Step-by-step explanation:

Here in this question, we need to find out the perimeter of the rectangle because it represents the length of boundary

since,

length = 40m

width = 10m

perimeter of rectangle = 2(length+width)

hence,

length of fence will be = 2(40+10) = 100m

Answer 2

The required length of the fencing is 60m

Explanation:

From the given data, we have,

Length = 40 m

Width = 10 m

$Perimeter =2( Length+ Width)$

Substituting the values, we have,

$Perimeter =2( 40 + 10)$

Simplifying, we get,

$Perimeter =2( 50)=100m$

It is also given that one of the length is along the boundary wall of his house.

Hence, let us subtract the length 40 m from the perimeter.

Thus, we have,

$Perimeter = 100-40=60m$

Hence, the required length of the fencing is 60m
