Step-by-step explanation:

A = 1/2*h(base + base)

First step, plug in your numbers:

1/2*(3)(5 + 9)

Add inside the parenthesis:

1/2*(3)(14)

Multiply 3 x 14:

1/2*(42)

Lastly, multiply:

A = 21 m^2

Hope this helps you :)

Hey Mate ,

In this particular question we have to find the area of a trapezoid.

The formula for finding the area is 1/2(a+b)h

Here ,

  • A :- 5m
  • B :- 9m
  • H :- 3m

Now putting all the values in the formula

Area :- 1/2(5+9)3

Area :- 21m²
