Question

A field measures 450m in length and 250m in breadth what will be cost of fancing at rs 50 paise per meter

Answer 1

Hello

Here is your answer

Perimeter of fied =2(l+b)

=2(450+250)

=2(700)

=1400m

Cost of fencig 1 meter=50paise

Cost of fencing field=1400*50=70000paise=Rs.700

If it really help you please mark me as brainliest

Answer 2

We will first calculate the perimeter

2 (l + b) is the formula

So put the values now

2 (450 + 250)

=2 (700)

=1400m

Now we will first calculate the cost in paise and then change in m

So

1400×50=70000 paise

In rupees

70000 ÷ 100=700 rupees

As 1 paise is equal to 1/100 rupees
