A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk
S_A_V [24]

Answer:

Patrick walk approximately <u>112 yards</u>.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

Diagonal = \sqrt{length^2+width^2}

Diagonal = \sqrt{100^2+50^2}

Diagonal = \sqrt{10000+2500}

Diagonal = \sqrt{12500}

Diagonal = 111.80

Therefore, Patrick walk approximately 112 yards.

A rectangle has a length that is 9 feet less than four times its width. Its area is 90 square feet
kramer

Answer:

The length of rectangle is 15\ ft

The width of rectangle is 6\ ft

Step-by-step explanation:

Let

x-----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

A=xy

A=90\ ft^{2}

so

90=xy -----> equation A

x=4y-9 -----> equation B

substitute equation B in equation A and solve for y

90=(4y-9)y

4y^{2}-9y-90=0

using a graphing calculator

The solution is

y=6\ ft

Find the value of x

x=4y-9  -----> x=4(6)-9=15\ ft

Need some answers for this one
Schach [20]

Answer:

20.6

Step-by-step explanation:

Since the diameter of each circle is 4, the dimensions of the rectangle is 8x12

The area of the whole rectangle is 96

Now we need to find the area of the circles

The area of 1 circle is 2^{2} *\pi =12.56...

So the area of all 6 circles is 12.56*6= 75.39...

So to find the area of yellow you have to subract the area of circle from the overall area of the rectangle

96-75.4=20.6
