Answer: 216 unit^2

Step-by-step explanation:

By Pythagoras theorem

AB^2 + BC^2 = AC^2

(3x)^2 + (4x)^2 = (30)^2

9x^2 + 16x^2 = 900

25x^2 = 900

x^2 = 36

x = 6

AB= 3x= 3(6)= 18 -------------------------Height

BC= 4x= 4(6)= 24 ------------------------Base

Area of triangle = 1/2 x Base x height

                           = 1/2 x 24 x 18

                           = 12 x 18

                           = 216 unit^2

Hope it helped
