Question

The sides of a rectangular field are in the ratio 3:2.If the area of the field is 3456 sq.m.Find the cost of fencing the field at 3.50 per metre.

Answer 1

LET THE SIDES BE 3X AND 2X

THEN

3X×2X=6X^2=3456

X^2 = 576

X = 24

Perimeter = 2(24×2+24×3)= 240 metre

COST OF FENCING = 240×3.50 = ₹ 840

Answer 2

area=l×b. 3456=3x×2x. . x²=3456/6. x²=576. x=24. then 240×3.50=840
