I'm not sure if there was supposed to be a variable in there somewhere, but I did my best to explain. Hope this helps!
Answer:
22.8
Step-by-step explanation:
the rectangular has :
the length CD =√[(3+3)²+(0-5)²]
= √(36+25) = √61 = 7.8
the width BC =√[(5-3)²+(3-0)²]
=√(4+9 =√13 = 3.6
so, the perimeter = 2(7.8 + 3.6)
= 2× 11.4 = 22.8
To find the number of red bricks used, you can create a part to part to whole ratio from the simple ratio of red to grey brick they give.
Then, use the total to create an equivalent ratio with the actual total number of bricks (140).
<u>5 red </u> <u>100 red</u>
<u>2 grey</u> = <u>40 grey</u>
7 total 140 total
<u>
</u>Each time, the simple ratio was multiplied by 20 to get the actual totals for each color.
<u>
</u>There were 100 red bricks used.<u>
