Answer:
his dad was cutting the grass for 1 hour and 4 minutes i hope this helps
Step-by-step explanation:
You didn’t post the options but that is also equal to 1.0 x 10^-6
Let the width be x, then the length is 2x
2(x + 4 + 2x + 4) = 46
(3x + 8) = 46/2 = 23
3x = 23 - 8 = 15
x = 15/3 = 5 ft
Therefore, width is 5 feet and length is 2(5) = 10 feet
