How would you calculate the area and perimeter of 3yd 6yd 5yd 10yds
spayn [35]
Okay, start with the smaller square, you know the side length is 3 and that the width is 5, multiply this together:
3 * 5 = 15

That's the smaller left side of this shape, now the bigger side, divide the 10 yards at the bottom by 2 to properly represent the other side then multiply this by the 6 over there.
5 * 6 = 30

Conclusion for Area: After adding the results the answer should be 45.

The perimeter is solely adding all the sides together. You have a 10, two 5's, one 6, and two 3's. Add this together:

10 + 5 + 5 + 6 + 3 + 3 = 32

Conclusion for Perimeter: So the perimeter would be 32.

I hope this helps in someway, have a great rest of your day! ^ ^

A zoo in oklahoma charged $22 for adults and $15 for children. During a summer day, 732 zoo tickets were sold, and the total rec
Vlad [161]

Answer: Cost of tickets for adults = $22

Cost of tickets for children = $15

Total number of tickets sold = 732

Total receipts = $12,912

Let x be number of adult ticket's sold and y be the number of child ticket's sold.

Therefore, we have:

x+y=732       --------------- equation 1

x=732-y

Also, we have:

22 x+15y=12,912

Now, let's substitute the value of x:

22 (732-y)+15y=12912

16104-22y+15y=12912

16104-7y=12912

7y=16104-12912

7y=3192

y=\frac{3192}{7} =456

Now, let's substitute the value of y=456 in equation 1, we have:

x+456=732

x=732-456

x=276

Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
