the width of Davids rectangular tent is 5 feet. the length is twice the width. Davids rectangular air mattress measures 3 feet by 6 feet. if David puts the air mattress in the tent, how many square feet of floor space will be available for the rest of his things?



Answer :

Tent:
Width = 5
Length = 10  so 5x10 = 50

Air mattress:
3x6 = 18

So 50 - 18 = 32 feet. 
David will have 32 feet of space in the tent leftover for his other things.
