Work out the area of triangle ABC.
SVETLANKA909090 [29]

Answer:

4 cm²

Step-by-step explanation:

Area = ½.bh

b = base (cm²)

h = perpendicular height, i.e. BD (cm²)

h^{2}  = (2 \sqrt{5} )^{2}  - (3 \sqrt{2} )^{2} \\  {h}^{2}  = 20 - 18 \\  {h}^{2}  = 2 \\ h \:  =  \sqrt{2}

b \:  =  3\sqrt{2}  +  \sqrt{2}  \\ b \:  = 4 \sqrt{2}

Area \:  =  \frac{1}{2} .(4 \sqrt{2} )( \sqrt{2} ) \\ Area \:  =4
