Explanation for the questions:
For number 12 take 50 and multiply it by 4 which is 200
For number 13 take 4 and multiply it by 4 which is 16
For number 14 take 4 and multiply it by 6 which is 24
For number 15 take 10 and multiply it by 5 which is 50
For number 16 take 75 and multiply it by 34 which is 2550
Tip:
If two numbers are given then it must be a rectangle. The formula for finding area of a rectangle is P = L x W
For example 20m is length and 5m was width so its area is 100m²
2nd Tip:
If only one digit is given it must be a square. The formula for finding the area of a square is A = S X 4
For example 4m is the side so its area is 16m²
Here's another example 6 is the side so its area is 24
