Answer 1

Hey mate, here's your answer

Answer 2

Answer:

Ratio of Length and Breadth=7:4

Let Ratio=7x & 4x

Fencing around it means on its sides Total sides length is PERIMETER

Cost of Fencing=₹25 per/m

Total Cost=₹3300

Perimeter=3300/25=132 m

Perimeter of rectangle=2(L+B)2(7x+4x)=1322×11x=13222x=132x=132/22x=6

• Length=7x

6×7=42 m

• Breadth=4x

4×6=24 m
