Question

I am very confused by this question. I need some help.

Answer 1

78.6

Explanation:

this is the rectangle

17

————

14 | _ | 14

|__ | |__|

4.7 5.2

so we 14+14=28

28+17=45

then we multiply 8.3 by 2 cuz we have it on both sides 8.3×2=16.6

then we add 17 since it's a rectangle it has parallel sides so 45+17=62

next we add 16.6

62+16.6=78.6
