Question

 A triangular field has sides 210 m, 180 m and 230 m long. How many metres of wire is required to fence the field?

Answer 1

Three sides of a triangular field = 210m,180m and 230m

To fence the field , here perimeter of a triangle is calculated.

Perimeter of a triangle = adding of three sides

= 210+180+230 = 620m

Answer 2

210+180+230
=620m
