I need help please, For a test.

(1.2*5.8)+(3.6*.6)+(.8*5.8) = 15.8

Step-by-step explanation:

17.28 cm squared

Step-by-step explanation:

To start we can find the area of the whole rectangle

5.6*6.4=35.84

then we can take away the area in the middle, which to do we would need to find the other length of it

5.6-(1.2+.8)=3.2

then we can multiply the blank area

5.8*3.2=18.56

and then subtract it from the total area

35.84-18.56=17.28
