9ft^2

Step by step explanation:

Area is L × W

so the L would be 3 3/4 ft x 2 2/5ft

with that equation in mind

how do we multiply whole number fractions? well, we make them into improper fractions

3 3/4 becomes (4x3) +3 / 4

2 2/5 becomes (2x5) + 2 / 5

Those answers become

15/4 x 12/5

^ Our improper fractions then we multiply across

15/4 x 12/5

^ 15 x 12 = 180

& 4 x 5 = 20

the final fraction becomes 180/20 and we can simplify that by 20

that becomes 9/1 = 9ft^2
