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?

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

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
