Question

The table shows the dimensions and the numbers of blades of grass on four rectangular pieces of sod. Select and drag the pieces of sod in order from greatest to least grass density, with greatest at the top and least at the bottom.

Answer 1

Answer: D, C, A, B

===============================================

Step-by-step explanation:

• Rectangle A has area 4*3 = 12 square feet. Divide the number of blades of grass over this area to get a density of 34188/12 = 2849. So the density for rectangle A is 2849 blades per square foot. Put another way, one square foot of rectangle A contains about 2849 blades of grass.
• Rectangle B has area 5*4 = 20 square feet and density 56340/20 = 2817 blades per square foot.
• Rectangle C has area 6*3 = 18 square feet and density 52632/18 = 2924 blades per square foot.
• Rectangle D has area 4*2 = 8 square feet and density 25248/8 = 3156 blades per square foot.

The density order from greatest to least is therefore: D, C, A, B
