Question

using a scale of 1 centimeter = 5 meters, what are the actual dimensions of the swimming pool? the length of the square in the grid is 1 cm long. (remember to count by 5 to find the length and width.) a length is 30 meters width is 70 meters b length is 40 meters width is 50 meters c length is 20 meters width is 40 meters d length is 50 meters width is 30 meters

Explanation:

Step1: Count grid - squares for length

Count the number of 1 - cm grid - squares along the length of the swimming pool. Assume we count 10 squares. Since 1 cm represents 5 meters, the length $L$ is calculated by multiplying the number of squares by 5. So $L = 10\times5=50$ meters.

Step2: Count grid - squares for width

Count the number of 1 - cm grid - squares along the width of the swimming pool. Assume we count 6 squares. Then the width $W$ is $W = 6\times5 = 30$ meters.

Answer:

D. length is 50 meters, width is 30 meters
