#1**+2 **

1)

For the first figure, we can divide it into two triangles on either end and a rectangle in the middle

The triangle on the left has a base of 3 and a height of 6

So....its area is (3 * 6)/2 = 9 units^2

The rectangle in the middle has a base of 4 and a height of 2

So.....its area is 4 * 2 = 8 units^2

The triangle on the right has a base (at the top) of 4 and a height of 2

So...its area is (4 * 2) / 2 = 4 units^2

So......the total area is [ 9 + 8 + 4 ] = 21 units^2
