Question

The ratio of the length and breadth of your class room is 7 : 5; if the perimeter of the class-room is 96 metres, then find the length and breadth of your class room.​

Answer 1

Answer:

length = 7x

breadth =5x

perimeter of rectangle = 2(l+b)

a/q. = 2(7x + 5x) = 96m

2(12x) = 96m

24x = 96m

x = 96/24m

x = 4 m

length = (7x4) = 28m

breadth = (5x4) = 20m
