Answer:
The number of bulbs planted in the garden having side length of 8 feet is 320.
Explanation:
Given as :
The side length of square shaped garden = x ft
The number of tulip bulbs Cindy's will plant at per square foot = n = 5
Let The number of bulb to be panted for side length of garden = L = 8 feet
Now, According to question
Since the garden is of square shaped ,
So, The area of garden = area of square = side²
I,e The area of garden = x × x ft²
Now, if the side length = L = 8 feet
So, The area of garden = L × L ft²
I.e The area of garden = 8 × 8 ft² = 64 square feet
Now, Again
∵ For the area of 1 square feet , the number of bulbs planted = 5
∴ For the area of 64 square feet , the number of bulbs planted = 5 × 64
I.e For the area of 64 square feet , the number of bulbs planted = 320
Hence The number of bulbs planted in the garden having side length of 8 feet is 320 . Answer
