Question

a rectangular public Park with length 140 metre and breadth 90 metre is to be fancy 3 round of wire concealed are to be put how much water is needed​

Answer 1

Answer:

length of park = 140m

breadth of park = 90m

wire needed = a

perimeter = b

b = 2(l+b)

2(140+90)

2(210)

420m

a = perimeter*3

b*3

420*3

1260m

so, 1260 meter wire will be needed to fence the park three times when length of park is 120 meter and breadth is 90 meters .

Step-by-step explanation:

Answer 2

Ur Answer here,

We know that perimeter = 2×(l+b)

Now,

l (length) = 140m

b (breadth) = 90m

so,

Perimeter = 2×(140+90)

Perimeter = 2×(230)

Perimeter = 460m

Now,

According to question,

3 rounds of fencing wire to be put.

so,

3×460 = 1380
