Answer 1

there is a narrow rectangular plot, reserved for a school, in mahuli village. the length and breadth of the plot are in the ratio 11:4. 
let the common multiple be x 
the length will be 11x 
breadth = 4x 
Perimeter = 2(L+B) 
=2(11x+4x) 
= 2*15x
=30x 
at the rate Rs 100 per meter 
30x * 100 = 3000x 
3000x= 75000 
3x=75 
x=25 
11x = 11*25 = 275m 
4x=4*25 = 100 m 
275m & 100m are the dimensions of the plot

❤️I hope it help you❤️

Answer 2

Let,the length be 11x and breadth be 4x
according to the condition,
2( l + b) =2(11x +4x) =75000÷100
22x + 8x =750
x = 750/30
x =25
Breadth= 4×25 = 100m
length= 11 × 25 = 275m
