Answer:

20 square inches

Step-by-step explanation:

First you have to find what the length and width is, of course.

Personally, I used guess and check. I drew a rectangle and started multiplying things until I got something that ends up matching what the rectangle has to be. 2 and 10. 2 x 5 = 10. and 2+2+10+10=24 (aka the perimeter) so i then multiplied 2x10 because length x width = area

2x10 = 20 so there you have it, that's your area

NeTakaya

Answer: 168 child tickets were sold.

Step-by-step explanation:

Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.

Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x

Total tickets = x+4x+2x = 7x =294

$\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42$

Number of child tickets = 4(42) = 168

Hence, 168 child tickets were sold.
