Tom bought a rectangular piece of land thatwas 3 miles long and 2 miles wide . Half of the land could be farmed . How many square milescould not be farmed .

What didn't you understand about the answer I posted a few minutes ago?

Well, if half of the land could be farmed, then the other half couldn't be farmed. So, let's calculate the area of the whole land first: 3 miles (length) x 2 miles (width) = 6 square miles. Since half of the land could be farmed, that means 6 square miles / 2 = 3 square miles could not be farmed. Just remember, even if it can't be farmed, it could still be the perfect spot to have a picnic or play a game of catch!

To find the area that could not be farmed, we need to subtract the area that could be farmed from the total area of the rectangular land.

The total area of the rectangular land can be found by multiplying its length and width. In this case, the length is 3 miles and the width is 2 miles, so the total area would be:

Total area = length × width
Total area = 3 miles × 2 miles
Total area = 6 square miles

Now, since half of the land could be farmed, we can find the area that could be farmed by dividing the total area by 2:

Area that could be farmed = Total area ÷ 2
Area that could be farmed = 6 square miles ÷ 2
Area that could be farmed = 3 square miles

Finally, to find the area that could not be farmed, we need to subtract the area that could be farmed from the total area:

Area that could not be farmed = Total area - Area that could be farmed
Area that could not be farmed = 6 square miles - 3 square miles
Area that could not be farmed = 3 square miles

Therefore, 3 square miles could not be farmed.
