Answer:
There are a total of 84 yellow corns and
840 white corns planted in the garden.
Step-by-step explanation:
Number of plants in each row = 42
Number of rows of yellow corn = 2
Number of rows of white corn = 20
To find the total number of yellow corns planted in the garden, we need to add the number of plants in each row 2 times.
i.e. 42 + 42 = 84
OR
we can say the following:
Total number of yellow corns planted in the garden = Number of rows of yellow corn
Number of plants in each row
![\Rightarrow 2 \times 42\\\Rightarrow 84](https://tex.z-dn.net/?f=%5CRightarrow%202%20%5Ctimes%2042%5C%5C%5CRightarrow%2084)
To find the total number of white corns planted in the garden, we need to add the number of plants in each row 20 times.
i.e. 42 + 42 + 42 + ....... + 20 times
OR
we can say the following:
Total number of white corns planted in the garden = Number of rows of white corn
Number of plants in each row
![\Rightarrow 20 \times 42\\\Rightarrow 840](https://tex.z-dn.net/?f=%5CRightarrow%2020%20%5Ctimes%2042%5C%5C%5CRightarrow%20840)
Hence, there are a total of 84 yellow corns and 840 white corns planted in the garden.
