The correct answer is

1330

Given Data:

  • Diagonal BD = 70 cm
  • AL (perpendicular to BD) = 17 cm
  • CM (perpendicular to BD) = 21 cm

Step 1: Calculate the Area of Triangle ABD

Area = (1/2) × Base × Height

Area of △ABD = (1/2) × 70 × 17 = 595 cm²

Step 2: Calculate the Area of Triangle BCD

Area = (1/2) × Base × Height

Area of △BCD = (1/2) × 70 × 21 = 735 cm²

Step 3: Total Area of Quadrilateral ABCD

Total Area = 595 + 735 = 1330 cm²
