Question 4

Mathematics
1 answer:
lawyer [7]3 years ago

Answer:

18ft

Step-by-step explanation:

L = length

W = width

l = w + 2ft ; because the is 2 ft longer than width

The area of a rectangle is lw

You can take the first equation ( l = w + 2 ) and plug it in lw

like this: lw ---> (w+2)w = w^2+2w

then from the question you get: w^2+2w=19.25

you use the quadratic formula and get w = 3.5

then from the first equation, you get l = 3.5+ 2 so the length is 5.5

lastly, you use the perimeter formula: 2(l+w) so 2(9) = 18

so 18ft

guajiro [1.7K]
With that information you can determine how far the park is from the football field.

Call h the height of the triangle, x the distance from the park to the football field and y the distance from the park to the home of Kristen.

Using Pithagora's theorem, ou can state this system of equations:

1) From the complet triangle: x^2 + y^2 = (8 + 2)^2 = 10^2 = 100

2) From the triangle whose hypotenuse is the distance from the park to the football field:

x^2 = 8^2 + h^2

3) From the triangle whose hypotenuse is the distance from the park to the home of Kristen:

y^2 = 2^2 + h^2

To solve the system start by subtracting equation 3) from equation 1) =>

x^2 + y^2 = 100
y^2 = 4 + h^2
---------------------
x^2 = 100 - 4 - h^2

x^2 = 96 - h^2

Now sum this result to equation 2

x^2 = 96 - h^2
x^2 = 64 + h^2
---------------------
2x^2 = 96 + 64

2x^2 = 160

=> x^2 = 80

=> x = 8.94
