Area is the measure of the amount of surface covered by something. Area formulas for different shapes are sometimes different, but for the most part, area is calculated by multiplying length times width. This is used when calculating area of squares and rectangles. Once you have the number answer to the problem, you need to figure out the units. When calculating area, you will take the units given in the problem (feet, yards, etc) and square them, so your unit measure would be in square feet (ft.2) (or whatever measure they gave you).
Step-by-step explanation: Marcus goal is 80 miles for the week. he has already completed 25 miles of that goal so you would subtract 25 from 80 then you would find the miles still left
Robert is 13 and his brother is 3 y.o. X... brother’s age X+10... Robert’s age X+10+2... Robert’s age in 2 years X+2...Brother’s age in 2 years X+10+2/x+2=3 X=3 X+10=13
