Question

a man has to fence his field all around whose limensioname are breadth=10m
length=25m

if he has 50m wire en how much more length of wire does he need
​

Answer 1

Answer:

You will need 20m of wire more

Step-by-step explanation:

Perimeter of Field = 2(l+b)

                              = 2(25 + 10)

                              = 2*35

                              = 70m

You already have 50m of wire so you will need 20m of wire more

Answer 2

Answer:

$2 \times( l + b) \\ 2 \times( 25 + 10) \\ 2 \times 35 = (70)$
