Answer:
A. 80
Step-by-step explanation:
Length of rectangular section of a wall = 90 inches
Width of rectangular section of a wall = 72 inches
Area of rectangular section of a wall = [tex]Length \times width[/tex]
= [tex]90 \times 72[/tex]
= [tex]6480 inches^2[/tex]
Each photo needs a space of approximately 8 in. by 10 in.
So, area of each photo = [tex]Length \times width[/tex]
= [tex]8 \times 10[/tex]
= [tex]80 inches^2[/tex]
Now he number of photos that can be hung on the section of the wall:
[tex]\frac{\text{Area of rectangular section of wall}}{\text{Area of each photo}}[/tex]
[tex]\frac{6480}{80}[/tex]
[tex]81[/tex]
So, 80 estimate best approximates the number of photos that can be hung on the section of the wall.
