landen's front yard lawn measures 20 feet by 8 feet. he counts to find that there are 120 blades of grass per 1 square inch. how many blades of grass are in the entire lawn?

Respuesta :

Answer:2764800

Step-by-step explanation:First step is to convert feet into inches:

1 foot = 12 inches

20feet = 20*12=240 inches

8feet = 8*12=96 inches

Now we can calculate total area:

A = height * width

A= 240 * 96

A=23040 inches²

We know the amount per one inch² and we need to find out total number of blades:

1 inch²                          120 blades

23040 inches²               x blades

Now we cross-multiply numbers:

1*x = 23040 * 120

x= 2764800

There are total of 2764800 blades in the entire law
