Answer 2

Answer:

Step-by-step explanation:

Case I -

Base = b

Height = h

         h = b/2

Area = 200 sq. cm.

b X h = 200 sq. cm.

b X b/2 = 200 sq. cm.

      b^2 = 400

          b = 20 cm.

h = b/2

  = 20/2

  = 10 cm.

Case II -

Base = b

     b = 5x

Height = h

        h = 2x

Area = 360 sq. cm.

b X h = 360 sq. cm.

5x X 2x = 360 sq. cm.

   10x^2 = 360 sq. cm.

       x^2 = 36

           x = 6 cm.

b = 5x

  = 5(6)

  = 30 cm.

h = 2x

  = 2(6)

  = 12 cm.
