  1. Let ∆ABC and ∆ABD be on the same base AB and between the same parallels AB and CD. Then the relation between areas of triangles ABC and ABD will be
    1. ∆ABD =
      1
      ∆ ABC
      3
    2. ∆ABD =
      1
      ∆ ABC
      2
    3. ∆ABC =
      1
      ∆ ABD
      2
    4. ∆ABC = ∆ABD
Correct Option: D

The areas of triangles on the same base and between the same parallel lines are equal.
∴ ∆ABC = ∆ABD
298. (2) Perimeter of rhombus
= 4 × side

∴ Each side =
240
= 60 metre
4

Distance between parallel sides = 20 metre
∴ Area of rhombus = 60 × 20 = 1200 sq. metre
