Question

a traingular field has the dimensions 40m,30m and 20m long respectively. find the length of fencing wire that goes round it 3 times.

Answer 1

Step-by-step explanation:

We need to find its perimeter

So,

Perimeter of triangle=Side+Side+Side

Hence

$40 + 30 + 20 = 90$

Now perimeter = 90m

90×3=270m

270 m is your answer
