Answer:
4 parts
Step-by-step explanation:
Since, Each part is equal to 1 ÷ 4th of the total area of rectangle.
Thus, 2 parts of rectangle = 2 ÷ 4 = 1 ÷ 2nd part = half of area of rectangle.
3 parts of rectangle = 3 ÷ 4th of the rectangle.
Similarly 4 parts of rectangle = 4 ÷ 4 = 1 part of rectangle which is equal to whole rectangle.
Hence, Rectangle is divided into 4 parts.
9+12=m or 9+12=21
this is because when we start with m-9=12 we know that m is supposed to be the sum of 9 and 12.
if we check our work we will see this
9+12=21
m-9=12
21-9=12
