Krista is planning to mow her grandparents lawn the rectangular yard is 10 yards by 12 yards but there is a square patio that has 12 foot sides in the middle of krista kenmo 15 square feet per minute about how long will it take to finish the yard

First fine the total area of the yard 10 yards x 12 yards = 120 yards^2 Now find the area of the patio in yards 1 yard = 3 ft and each side of the patio is 12 ft --> 4 yards so the patio sides are 4 yds 4 yrds x 4 yrds = 16 yards To find the area of the yard only: 120 yards^2 - 16 yards^2 = 104 yards^2 Krista needs to mow 104 yards^2 total. And she can do 15 ft^2 per minute need the same units so convert the yards to feet 104 yards^2 x 3 ft/yard X 3 ft/yard = 936 ft^2 To find the minutes, divide the total by the amount she can do in one minute: 936 ft^2/15 ft^2 = 62.4 62.4 minutes

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!

Ithink it would be 160 people
