The area of a rectangular field is equal to 50 square meters. Its perimeter is equal to 30 meters. Find the width of this rectangle. Options
A) 5 B) 10 C) 15 D) 20 E) 25
L * W = 50 : area , L is the length and W is the width.   2 L + 2 W = 30 : perimeter   L = 15 - w : solve for L   (15 - W) * W = 30 : substitute in the area equation   W = 5 and L = 10   correct answer 5
