Question:

What is the perimeter of a rectangle when the length= 30 cm and the width=20 cm?

Answer:

The perimeter is when you add all four sides together. Two of the sides are the length (30). So 30+30= 60 cm, but we aren't done yet. Two of the sides are the width (20). So 20+20=40 cm. Now we have to add the two answers we got together so 60+40= 100 cm. The perimeter is 100 cm. (You also could ass 30+30+20+20= 100 cm).

Answer:

If the equation is 9-b, and b=8, you would substitute 8 in for b. So then, the problem would be 9-8 and 9-8= 1. So your answer would be 1.

Question:

Adam has $800 in his bank account. He received a check from his job for $1,200 and he puts that into his bank account. How much money does he have in his bank account after he puts the check in his bank account?

Answer:

In this problem, Adam is adding more money to his bank account. So, therefore, we have to use addition to solve the problem. He already has $800 and he adds $1,200. So 800+1,200= 2,000. Adam now has $2,000 in his bank account.
