Answer:
1,960,000 square feet
Explanation:
First let's round 679 to the nearest hundred. To do this we look at the 10s digit. If it is 5 or greater, we round up to 700 (because it is past halfway between 600 and 700), and is not we round down back to 600.
The 10s digit of 679 is 7, which is greater than 5. Therefore 679 rounded to the nearest hundred is 700.
Now let's look at 2828. The 10s digit here is 2, which is smaller than 5, therefore we round back down to 2800, which is closer than 2900.
Now we have 700 and 2800. To find the area, (assuming the yard is a rectangle) we multiply the length by the width together (these two values). 700x2800 = 1,960,000 square feet.
Hope this helped!
