A rancher wants to construct a rectangular enclosure for some livestock. Only three sides must be fenced, since a river will form the fourth

side. If he uses 100m of fencing, what is the maximum area of the enclosure?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
