quester [9]

Answer:

x^2-50x+456=0

Step-by-step explanation:

GIVEN: A 100\text{ foot} fence is used to enclose a rectangular land plot. If the area of the land plot is 456\text{ feet}^2.

TO FIND: equation to determine the length x of the land plot.

SOLUTION:

total length of fence =100\text{ foot}

let the width of land plot be y

perimeter of plot =2(x+y)=100

                            x+y=50

area of rectangular plot =\text{length}\times\text{breadth}

                                       xy=456

                                      y=\frac{456}{x}

putting value of y

x+\frac{456}{x}=50

x^2-50x+456=0

Hence required equation to get length x of land plot is x^2-50x+456=0

on solving

x=38,12

possible length of land plot is 38\text{ foot} and 12\text{ foot}

Answer:

A = 104 ft²

Step-by-step explanation:

We're given that the width of the rectangle is 8 so that's the value of w. All we have to do is just plug in 8 into the equation:

A=w²+5w

A=(8)²+5(8)

A=64+40

A = 104 ft²
