Thee area of the square is __ square cm. The area of the square and the length of its side __ directly proportional quantities.
2nd __ has to be "are" or "are not"
The area of the square is 4 square cm. The area of the square and the length of its side are directional proportional quantities.
Step-by-step explanation:
A square has equal sides. We have to do length times height to get the area. 2*2 is 4. The area is 4 cm. And since this value needs to be multiplied by itself to get the area, it IS proportional.
Katherine used 1479 minutes call in the last 6 months.
So, the average monthly call that Katherine made is minutes.
Now, there are two plans for mobile recharge.
