1 answer:
The area of the part with grass is 20 square meters.
Step-by-step explanation:
Step 1:
We can find the area of the grass by subtracting the area occupied by the sand from the area of the entire park.
The area of a rectangle is obtained by multiplying the length with the width of the rectangle.
The area of the part with grass = The area of the entire park - The area of the part with sand.
Step 2:
The entire park has a length of 6 m and a width of 4 m.
The area of the entire park square meters.
The area of the part with sand has a length of 2 m and a width of 2 m. It is actually a square.
The area of a square is the square of the side length.
The area of the part with sand square meters.
Step 3:
The area of the part with grass = The area of the entire park - The area of the part with sand.
The area of the part with grass .
The area of the part with grass is 20 square meters.

Then we would have 4 possible values for the last letter and 7 remaining letters in the middle of the word:
The probability is calculated by the division of the number of words we want over the total number of words:
