Both areas are rectangles.
The are of a rectangle can be calculated by multiplying its lngth by its width.
The grey area has dimensions of 6 inches by 5 inches, so its area is:
[tex]A_{grey}=(6in)\times(5in)=30in^2[/tex]
a. The grey area is 30 square inches.
The red area has dimensions of 6 inches by 4 inches, so its area is:
[tex]A_{red}=(6in)\times(4in)=24in^2[/tex]
b. The red area is 24 square inches.
The total area is just the sum of the grey and the red areas:
[tex]A_{total}=A_{grey}+A_{red}=(30in^2)+(24in^2)=54in^2[/tex]
c. The total area is 54 square inches.
