Question

The length and breadth of a
breadth of a rectangular
field are in the ratio 4:3 if perimeter is 210m, find its dimensions​

Answer 1

• Let l and b be x say
• then, the ratio becomes = 3x : 4x

Perimeter of rectangle = 2( l+b ) = 210m

2 ( 3x+4x ) = 210m

2 ( 7x ) = 210m

14x = 210m

x = 210m / 14

x = 15m

Length (3x) = 3*15m = 45m

Breadth (4x) = 4*15m = 60m
