Answer:
The estimated area is [tex]416\frac{13}{16}\ ft^{2}[/tex]
Step-by-step explanation:
we know that
To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3
step 1
Convert the dimensions to an improper fractions
[tex]9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft[/tex]
[tex]14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft[/tex]
step 2
Find the area of one wall
[tex](\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}[/tex]
step 3
Multiply the area of one wall by 3
[tex](3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}[/tex]
step 4
Convert to mixed number
[tex]\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}[/tex]
