Answer:
600.4 cm^2
Step-by-step explanation:
first we should find the base of samller triangle
hypotenuse = 35 cm
one side = 30 cm whereas other has be be find
using pythagoras theorem
a^2 + b^2 = c^2
30^2 + b^2 = 35^2
900 + b^2 = 1225
b^2 = 1225 - 900
b^2 = 325
b =
b =
area of big triangle
base = 22 +
area of a triangle = base * height / 2
= 30 (22 + ) /2
=30*22 + 30* / 2
=660 + 540.83 / 2
=1200.83 / 2
=600.415
=600.4 cm^2
