The length of a rectangle is 6m longer than its width. If the perimeter of the rectangle is 52m, find its area

1 answer:

4 0

If length is x, then width is 6+x
Perimeter = 2*(x + 6+x) = 52 
2*6 + 2*2x = 52 
4x = 52 - 12 = 40 
x = 40/4 = 10 

Area = length*width = 10*(6+10) 
Area = 10*16 = 160 meter square

The morning temp. In Atlanta, Georgia is 21 1/4 degrees. During the day it warms up 6 2/7 degrees. What is the new temp

pogonyaev

Answer:

27 15/28 degrees

Step-by-step explanation:

Since we are adding 21 1/4 to 6 2/7, we need to find the LCD, or, least common denominator, so that we can add 1/4 and 2/7 together.

1*4=4 1*7=7

2*4=8 2*7=14

3*4=12 3*7=21

4*4=16 4*7=28

5*4=20

6*4=24

7*4=28

Since we had to multiply 7 four times to get it equal to 28, we need to take 2/7 * 4/4. This will give you 8/28. Then, since we multiplied 4 seven times to get it equal to 28, we need to take 1/4 *7/7. This will give you 7/28. Finally, you need to add 8/28 and 7/28 since they now share the same denominator.

8/28 + 7/28=15/28

For our last step, we need to add the whole numbers together so the answer is complete.

21+6=27

27+15/28= 27 15/28 degrees
