Question

The window of a room is 20m long and 14m wide. If the carpenter works to

put a metallic frame around it which costs ₹120 per meter, then how much will
the metallic frame cost?

Answer 1

Length =20 m

Breadth =14 m

Perimeter =2(l+b)

2(20+14)=2*34=68 m

Given cost per m =120 rs

Then the total cost =68*120=8160 rs
