GIVEN :
- DIAGONAL of the quadrilateral = 10 cm
- Parallel sides = 5 cm and 4 cm
To find :
- AREA of the quadrilateral
According to the question,
→ Area of quadrilateral = ½ × diagonal × sum of the length of the perpendicular sides
→ Area of quadrilateral = ½ × 10 × (5 + 4) cm²
→ Area of quadrilateral = 5 × (5 + 4) cm²
→ Area of quadrilateral = 5 × 9 cm²
→ Area of quadrilateral = 45 cm²
.°. Area of quadrilateral is 45 cm².
