Answer:
105 cm squared
Step-by-step explanation:
15×6 to get the rectangle =90
then we have a triangle left so you do 15- 9 for the base =6 and multiply that by hight (6×5=30) and since it's a triangle and not a square we have to divide that answer by 2 and we get 15. Add those together, we get 105. Hope that helped!
The cooper's weight as an adult dog will be 90 pounds.

What is percentage?</h3>
Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.
A typical method for calculating a percentage is the formula shown below:
- Determine the total amount of what you want to find a percentage.
- Divide the number to determine the percentage.
- Multiply the value by 100.
Calculation for the weight of Cooper as an adult;
Cooper's present weight is 20 pounds.
He will weigh about 350% as much as his current weight.
Calculate 350% of 20 pounds.
= (350×20)/100
= 70
The increment of the weight of Cooper will be 70 pounds.
Thus, the total weight is 20 + 70 = 90.
Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.
