Maggie found the area of the irregular figure by dividing it into a triangle and a rectangle.

33cm^2

Step-by-step explanation:

Rectangle:

5 x 6 = 30

Triangle:

1 side 6 - 3 = 3

2 side 7- 5 = 2

area of right triangle:

A = (ab) / 2

A = (3 * 2) / 2

A = 3

sum:

30 + 3 = 33

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
