To find the area of a trapezoid use the expression 1/2h (b1 + b2), where h represents the height b1 represents the length of the top base and b2 represents the length of the bottom base. what is the area of the trapezoidal table?

length 4ft and 3ft
height 2 ft in the center

7 ft²

Step-by-step explanation:

The formula for this is given in the problem

Plug in the given values

1/2 * 2 (4+3)

1*7

7 ft²

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
