Question

Find the area of the following figure​

Answer 1

Answer:

Answer:

Construction = Join A and c and then find ac by Pythagoras theorem

AB²+ BC² = AC²

5² + 12²= AC²

25+ 144 = AC²

169 = AC²

AC = 13m

Similarly, AD = 13m

Area of Δ ABC= Ar(ΔEAD) = 1/2 x 12 x 5 = 30 m²

Area of Δ ADC by heron's formula= 60 m²

Area of given figure = Ar(ΔABC)+ Ar(ΔADC) + Ar(ΔEAD) =( 30 +60 +30 )m²

Area of given figure = 120m²
