3. In class, you learned how to find the area of irregular shapes by breaking into regular shapes. For the picture below, you are going to calculate its area. For this problem, you must:

• Draw how you broke up the shape
• Show the work for how you found the area of each piece
• Calculate the total area from the pieces

Answer:

57.5

Step-by-step explanation:

if you break it down into smaller shapes, there's a semicircle, three triangles and a rectangle.

circle πr² = π 2² = 4π² = 39.5

triangle 1 bh = (3)(2) = 6

triangle 2 bh = (4)(1) = 4

triangle 3 bh = (2)(4) = 8

Add them all up to get total area

6 + 4 + 8 + 39.5 = 57.5
