you enclose a field using sections of fence with length of 15,20 and 25 meters estimate the area of the field

150 square meters

Step-by-step explanation:

Assuming that this field is triangular, we can multiply the two shortest sides together, and then divide by 2, because that is the formula for the area of a right triangle.

So 15 times 20 is 300

300 divided by 2 is 150

So we can estimate the area to be 150 square meters.

(Upon solving further, we realize that this is a right triangle, so our initial estimation is the exact area)
