50 ! what is the area of the composite figure?

280cm^

Step-by-step explanation:

1 square 10x10 = 100

1 rectangle 20x6 = 120

1 rectangle 18x4=72

subtraction of hallf of a rectangle 6x4=24 (half = 12)

100+120+72= 292

292-12=280

1 square at the top (10x10) 100

1 rectangle at the bottom(20x6)   120

1 rectangle in the middle with a missing part (18x4)= 72

4+5+3+? =18

?=18-12

?=6

The missing part is half of 6x4   24/2 =12

264cm^2

Step-by-step explanation:

1) 10x10 = 100

2)20x6 = 120

3)3x4=12

4)5x4=20

A=h_{b)b

        2

5)6·4      =12

    2

100+120+12+12+20=264

Hope this helps!
