Question

the length and breadth of a field are in the ratio 7.5 and its perimeter is 168 metre find the area of the field also find the cost of cultivating the field at the cost of rupees 4.75 per square metre

Answer 1

Hii frnd...

Let the length be 7x and breadth be 5x
Perimeter:2(l+b)
=2(7x+5x)
=2(12x)
=24x

A to Q
24x= 168
x= 7
Length= 49m
Bredth= 35m

Area of the field=L*B
=49*35
=1715 $m^{2}$

Cost for cultivating the field=1715*4.75
=8146.25 $m^{2}$ Rs.

Hope it helped u!!!
