Question

If it costs $1600 to fence a rectangular park of length 20 m at the rate of $25 per sq.m, find the bredth of the park and it's perimeter. Also, find the area of the park.

​

Answer 1

Answer:

Step-by-step explanation:

I am guessing you meant $25 per meter

Cost = Perimeter x The rate per meter

let the perimeter be x

1600= x x 25

1600/25=x

64=x

Now perimeter =x=64m

Perimeter=2(l+b)

64=2(20+b)

64=40+2b

64-40=2b

24=2b

24/2=b

12m=b

Now a =l*b

A=20*12

A=240 square meter

So perimeter =64m

Breath=12m

and area =240 square meter

Answer 2

Step-by-step explanation:

cost of fence=$1600

l=20m

b=X

1600=X×25

1600÷25=X

X=34

P=2×(I+B)

P=2×(25+34)

P=2×59

P=118m

A=l×b

A=25×35=
