The first one is 35 sq ft
Because A=LxW A=7x5
The second i don’t know because I can’t see the width
The third one is 432 sq in
because A=LxW A=18x24
The fourth is 21 sq. Yards
because A=LxW A=7x3
The fifth one is 84 ft sq.
Because (play area) = 4x3=12 (backyard) = 9x8= 72 and then you need to add 72+12 which gets you 84
