Answer 1

Answer:

33750 cm²

Step-by-step explanation:

Perimeter of triangle = 900 cm

Sum of terms = 3 + 4 + 5 = 12

First side of triangle = ( 3/12 x 900 ) cm = 225 cm

Second side of triangle = ( 4/12 x 900 ) cm = 300 cm

Third side of triangle = ( 5/12 x 900 ) cm = 375 cm

Area of rectangle = $\sqrt{s}{(s-a)}{(s-b)}{(s-c)}$

                             =  $\sqrt{450}{(450-225)}{(450-300)}{(450-375)}$

                             = 33750 cm²
