Jack's yard is a rectangle 105 feet by 212 feet. Using front-end estimation on the dimensions, what is an estimate of the area of this yard?
105x212=22,260
estimated=22,300
the real answer is 22,000 because its less than 500 so since its 200 you round down.
To estimate the area of Jack's yard using front-end estimation, we will consider only the front digits of each dimension.
The front-end estimation involves rounding the numbers to their nearest tens or hundreds and then multiplying the rounded numbers together to get the estimated area.
For the length dimension, which is 105 feet, round it down to the nearest ten to get 100 feet.
For the width dimension, which is 212 feet, round it down to the nearest ten to get 210 feet.
Now multiply the rounded dimensions together to get the estimated area:
100 feet x 210 feet = 21,000 square feet
Therefore, the estimated area of Jack's yard using front-end estimation is 21,000 square feet.
