Find the area of the following shapes:

Area = 20 square units

Step-by-step explanation:

=> We know that;

Base 1: 3 units

Base 2: 7 units

Height: 4 units

=> Now let's come up with a congruent base first:

= final base

10/2 = final base

5 = final base

=> Finally, Area of the trapezoid:

A = Final Base * Height

A = 5 * 4

A = 20 square units

Hope this helps!

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
