Question

The length and the breadth of a rectangular field are in the ratio 7:4. The cost of fencing the field at ₹ 25 per metre is ₹ 3300. Find the dimension of the field.

Ans) let the length be 7x and breadth is 4x.
=) 2(7x+7x) 25= 3300
=)50x × 11x= 3300
=) 11x = 3300÷ 50
=)11x=66
=) x= 66÷11
x=6
So length is 7×6= 42cm and breadth is 4×6= 24 cm.​

Answer 2

Answer:

length is 7xand breadth is 4x

Step-by-step explanation:

1).2(7x+7x)=25=3300

2.)50X×11X=3300

3)11X=3300÷50

4.)11X=66

5.)X=66÷11

X=6

length is 42 and breadth is 24
