Answer:

Step-by-step explanation:

For the first one, you can break apart the shapes to a square and a rectangle

The square is 49

The rectangle is 65

Add them together

The first one is 114

For the second one you can break it apart to a triangle and a rectangle

The rectangle is 4 x 12

The triangle is 0.5 * 8 * 4   [8 is 12 - 4 (base)]

The rectangle is 48

The triangle is 16

Add them together

48 + 16 = 64

The second one is 64
