Question

Find the length of rectangle whose perimeter is 2300 m and breadth is 500m

Answer 1

let the length be x
perimeter equal 2300m
breadth equal 500m
perimeter of rectangle equal 2(x+b)
2300 equal 2(x + 500)
2300 equal 2x+ 1000
2300-1000 equal 2x
1300 equal 2x
1300/2 equal x
650 equal x
breadth equal 650
