figure (1)

3x1 = 3cm²

figure (2)

s =  \frac{a + b + c}{2}  =  \frac{2.5 + 2.5 + 2}{2}  = 3.5

area =  \sqrt{s(s - a)(s - b)(s - c)}

  \:  =  \sqrt{3.5(3.5 - 2.5)(3.5 - 2.5)(3.5 - 2)}

 \:  =  \sqrt{3.5 \times 1 \times 1 \times 1.5}

 \:  =  \sqrt{0.7 \times 5 \times 5. \times .3}

 \:  = 5 \sqrt{0.7 \times 0.3}

 \:  = 5 \times 0.458

 \:  = 2.290

total  \: area = figure (1) + figure (2)

 \:  \:  \:  = 3 + 2.290

 \:  \:  \:  = 5.290 \:  {cm}^{2}
