Presentation transcript:

Estimating Length and Area COURSE 2 LESSON 8-1 Choose an appropriate customary unit of length for estimating each measurement. a. an automobile An appropriate measure is feet. The length of an automobile is much less than a mile, but much greater than an inch. b. a computer keyboard An appropriate measure is inches. The length of a computer keyboard is less than a yard. 8-1

Estimating Length and Area COURSE 2 LESSON 8-1 Choose a reasonable estimate for the perimeter of a piece of paper: 40 in. or 40 ft. The edges of a piece of paper would be measured in inches. So 40 in. is the better estimate. 8-1
