Answer:
The area of the shaded part is 100 [tex]cm^2[/tex]
Step-by-step explanation:
Subtracting Areas:
We can find the shaded area by adding or subtracting areas.
We'll use the latter method.
The total shape is a rectangle of side lengths 15 cm and 10 cm. Thus its area is:
[tex]A_t=15\ cm\cdot 10\ cm=150\ cm^2[/tex]
The area of each non-shaded square is:
[tex]A_s=(5\ cm)^2=25\ cm^2[/tex]
The total non-shaded area is
[tex]2*A_s=50\ cm^2[/tex]
Thus, the shaded area is:[tex]A_{shaded}=A_t-2*A_s=150 - 50 = 100[/tex]
The area of the shaded part is 100 [tex]cm^2[/tex]
