Answer 2

Step-by-step explanation:

$\huge\fcolorbox{blue}{green}{Given}$

• Let length of rectangle be x m

• Ratio of length and Breadth=7 : 4

$\huge\fcolorbox{blue}{green}{Formulas used}$

• Perimeter = 2( l + b )

$\huge\fcolorbox{blue}{green}{Solution}$

• x / Breadth = 7 /4

• Breadth = 4x / 7

Cost of fencing 1m = Rs. 25

Cost of fencing the field =Rs. 3300

Perimeter of rectangle × cost of fencing 1cm =

cost of fencing the field

➣ 2(l + b) × 25 = 3300

➣ 50(l + b) = 3300

➣ l + b = 66

➣ x + 4x / 7 = 66

➣ 11x = 66 × 7

➣ x = 42

➣ Length = 42m

➣ Breadth = 24m.
