Mr. Lopez has a new house and wants to put a fence around the perimeter of the yard. How many feet of fending will he need to buy if his yard is rectangular and measures 100 ft by 140 fa

560 ft

Step-by-step explanation: so if it is 100 ft and 140 ft you add them both to get 280 feet but you have the other side of the fence so 280*2=560

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
