Answer 2

Answer

96cm is the area of right angled triangle,and 156.8cm is the area of the figure on the right.But total area is 96+156.8=252.8cm

Step-by-step explanation:

Find Base in right angled triangle by H2=p2+b2 (2 is square).

(20)2=(16)2+B2

400=256+B2

400-256=B2

144=B2

12=B

Area=(1/2)(12)(16)=96cm

FINDING AREA OF FIRST TRIANGLE

PERIMETER=9+41+40=90

SEMI PERIMETER=90/2=45

HERONS FORMULA=S(S-A)(S-B)(S-C)( THIS EQUATION IS IN ROOT)

S IS SEMI PERIMETER AND A,B,C IS SIDE

29.5(29.5-20)(29.5-16)(29.5-23)

(29.5)(9.5)(13.5)(6.5)

24591.93(NOW TAKE THE ROOT OF THIS NUMBER)

156.818 is the area of first right triangle

adding both areas

156.818+ 96=252.818cm.
