Sadie is Landscaping a triangular area in her backyard to the nearest Foot how much fencing will Sadie need to enclose the area.

We need to fond the last missing side of this right triangle.

We need to use pythagorean theorem.

a^2 + b^2 = c^2

In this problem,

a = 10

b = ?

c = 14

Plug these numbers into the equation.

10^2 + b^2 = 14^2.

Square each term.

100 + b^2 = 144.

Subtract 100 from each side.

b^2 = 44.

Take the square root of each side.

b = 7 ft

we have to add together each side of the triangle to find the perimeter

10ft + 7ft + 14ft = 31 feet

The perimeter is 31 ft

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
