that?

HaydenwH:

i think that you would find the area for each individual piece then add them??

HaydenwH:

use the "25" for the length for all the rectangles in the row, then multiply tht by the width on top of each rectangle, find the are for the two squares and add all together

HaydenwH:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Florisalreadytaken agreed, but the question is if she has to paint both sides or just the outside? \(\color{#0cbb34}{\text{End of Quote}}\) since that is a "net" once folded bck to the right shape it will be closed up so you would only paint one side

HaydenwH:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @HaydenwH use the "25" for the length for all the rectangles in the row, then multiply tht by the width on top of each rectangle, find the are for the two squares and add all together \(\color{#0cbb34}{\text{End of Quote}}\) well "squares" smaller rectangles

TETSXPREME:

so what do i do? o;

BrokenMoon:

tet are u painting the inside or outside or both

snowflake0531:

do you still need help

HaydenwH:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @TETSXPREME so what do i do? o; \(\color{#0cbb34}{\text{End of Quote}}\) you still dont know how?

TETSXPREME:

smh yea i still need help

snowflake0531:

I suggest to first find the area of BCDF The width of that is 25, while the length is 13+16+13+16, which is 58 So, 25 times 58 equals 1450 Got that?

TETSXPREME:

yea

snowflake0531:

Then, you find A or E, since they are the same, looking at area. 13*16=208, so multiplied by 2, that is 416

snowflake0531:

So, 1450 + 416=....?

HaydenwH:

ok the height for all 4 rectangles is 25, the width is listed above them start by finding the area of the first....25X13

snowflake0531:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @snowflake0531 So, 1450 + 416=....? \(\color{#0cbb34}{\text{End of Quote}}\)

TETSXPREME:

1866?

TETSXPREME:

1866?

snowflake0531:

Whatever the calculator says. But, it says there are four chests, so, what is that multiplied by 4?

TETSXPREME:

7464

snowflake0531:

Sure, and then remember to add units, inches squared

TETSXPREME:

inch square? where ?

snowflake0531:

Because that's the unit. 7464 inches squared

TETSXPREME:

idk how i do that xD

snowflake0531:

You don't have to do anything... Do you know what units are?

TETSXPREME:

nope i failed kindergarten for a reason o;

snowflake0531:

I'll assume that as a no. Units are just to say what exactly is it. If you just say 7464, that's like a length, and I wouldn't know if it was 7464 miles or what. So, in the picture, it said, 'inches'. But then, because we were solving for area, we have to add the 'inches squared'. So, the answer is 7464 inches squared.

TETSXPREME:

Ah ty C:

Yw~!
