Question

(7) A rectangular plot has the measurement
of 25 m x 20 m. Find the length of the
wire required to fence it in two rows.​

Answer 1

Answer:

In the rectangle :

LENGTH = 25m

BREADTH = 20m

so, its perimeter is = 2(25 + 20)

= 2 × 45

= 90m.

So, the length of the wire required to fence the plot is 90m.

Answer 2

Answer:

Length of Fence (Two Rows) = 180m

Step-by-step explanation:

Length of Plot = 25m

Breadth = 20m

Length of Fence (Two Rows) = 2 × Perimeter of Plot

Length of Fence (Two Rows) = 2 × 2 × (l + b)

Length of Fence (Two Rows) = 2 × 2 × (25 + 20)

Length of Fence (Two Rows) = 2 × 2 × 45

Length of Fence (Two Rows) = 180m
