Question

Mr. Santiago wants to enclose a rectangular field with an area of 550 square meters. If the length of the field is 3 meters more than the width, find the amount of fencing materials needed to enclose the rectangular field.

Answer 1

Answer:

94 meters

Step-by-step explanation:

length=x

width=y=x-3

area=550

we know that area=x*y=550

x(x-3)=550

x^2-3x-550=0

x=(-(-3)+-root(3^2-4*1*-550))/2

x=(3+-47)/2

x=(3+47)/2

x=25

for fencing the material required is equal to the perimeter of the rectangle

i.e. 2(x+y)=2(25+22)=94meters

Answer 2

Answer:

94. metres is ur right answer
