The triangle inscribed on top of the larger shape has its dimensions as
Base = 2
Height = 3
Note that the two triangles are exactly alike. This means the area of the triangle shall be times two eventually.
[tex]\begin{gathered} \text{Areaof a triangle;} \\ A=\frac{1}{2}bh \\ b=2,h=3 \\ A=\frac{1}{2}\times2\times3 \\ A=3cm^2 \end{gathered}[/tex]
Also, note that the other shape at the bottom region has one side measuring 5 cm while the other side measures,
2 + 2 + 1 = 5 cm
Area of the square is
[tex]\begin{gathered} \text{Area of a square;} \\ A=l\times w \\ A=5\times5 \\ A=25cm^2 \end{gathered}[/tex]
The area of each shaded region is therefore,
A Triangle = 3 square cm
B Triangle = 3 square cm
Square = 25 square cm
