What is the area of this trapezoid a 50 in² b 108 in² c 126 in² d 192 in²

C 126 in²

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

b1 is the bottom base length = 12 inches

b2 is the top base length = (2+12+2) = 16 inches

h = height = 9 inches

A = 1/2 (12+16) *9

A = 1/2(28)(9)

A =126 in^2

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
