Help pls ;-;

What is the perimeter of the figure?


a. 180 in.

b. 64 in.

c. 65 in.

d. 72 in.

Answer 1

That answer would be 180 inches because Ethan just put 10 inches +48 inches +50 inches is 180 inches

Answer 2

180 in

Explanation:

The perimeter is just the sum of the lengths of the sides of the shape.

So all we need to do here is:

40+10+(40-18)+(50-10)+18+50.

I got (40-18) for the bottom of the top rectangle, the part that is poking out.

I got (50-10) for the right side of the rectangle that is poking out towards the bottom.

40+10+(40-18)+(50-10)+18+50

40+10+22 +40 +18+50

50 +62 +68

50+62+68

112+68

180

180 in

I'm going to post a drawing here to show the lengths I was talking about:
