Given :-
- A trapezium whose area is 105cm square and bases are 14cm and 7cm.
To find :-
- Altitude of trapezium
Solution :-
- Area of trapezium = 105 cm²
- Bases of trapezium = 14cm and 7cm
As we know that
→ Area of trapezium = ½ (a + b) × h
Where " (a + b) " is sum of parallel sides and " h " is Altitude.
- According to the question
→ Bases of trapezium = parallel sides
→ Area of trapezium = 105 cm²
→ ½ (a + b) × h = 105
→ ½ (14 + 7) × h = 105
→ ½ × 21 × h = 105
→ 21/2 × h = 105
→ h = 105 × 2/21
→ h = 10 cm
Therefore,
- Height of trapezium is 10cm
More to know :-
- Area of circle = πr²
- Circumference of circle = 2πr
- Perimeter of reactangle = 2(l + b)
- Perimeter of square = 4 × side
- Area of square = side × side
- Area of rhombus = ½ × product of diagonals
- Area of parallelogram = base × height
