Answer:
The total area covered by Liza and Abby is 44.5 ft².
Step-by-step explanation:
Area of a rectangle is
[tex]A=l\times w[/tex]
The area of pink blanket is
[tex]A=5\times 5.7=28.5[/tex]
Therefore the area of pink blanket is 28.5 ft².
The area of blue blanket is
[tex]A=6\times 4=24[/tex]
Therefore the area of blue blanket is 24 ft².
The area of a triangle is
[tex]A=\frac{1}{2}\times base\times height[/tex]
The common area is
[tex]A=\frac{1}{2}\times 4\times 4=8[/tex]
Therefore the common area of both blanket is 8 ft².
The total area covered by Liza and Abby is
[tex]28.5+24-8=44.5[/tex]
Therefore the total area covered by Liza and Abby is 44.5 ft².
