Question

Sheila has three strips of unfinished molding that she wants to use to frame the two pictures. Each strip is 36 inches long.

Assuming there is no wastage or overlap of molding, what is the minimum length of molding, in inches, Sheila still requires to frame both the pictures? Show your work and explain your reasoning in complete sentences.

Answer 2

@radar can you help me with this please?

Answer 3

I would imagine it's just the edges all added together. So you know the lengths of all 4 sides of both pictures in that image, just add them all together.

Answer 4

That's what she needs, then you can figure out what she has, (she has 3 pieces at 36 inches each) so find the total inches she has there, subtract it from what's needed, and that's your answer.

Answer 5

idk?

Answer 6

Where are you lost? What part of it do you not understand?

Answer 12

I'm working on it, give me a sec :)

Answer 13

Okay, you've got what she has. Good.
Now you need to find the total amount she needs.
For that you look at the image. It gives you 2 sides of each painting. By the looks of it we can assume that they are equal.
So for the one on the right: You're given 25 and 35 inches. (Side note, I'm hoping the other number of the one on the left was cut off, or that's gonna make things tricky)
So that's 25+35 to find the amount of molding needed for those two sides. You can then multiply that by 2 (or add it to itself) to find the total needed for the whole painting.

So the painting on the right is 25+25+35+35 inches of molding. (Or 2(25+35), same thing)

Answer 14

So thats the final answer?

Answer 15

No, that's only a part of the answer. The full answer is
What she has - (amount needed for right painting + amount needed for left painting)

You already know what she has, I just told you how to get the right, it's the same process for the left. Then plug in the numbers and do the math
