Find the altitude of a trapezium if the length of two bases are 4.6 cm and 2.4 cm respectively. The area of the trapezium is 42 cm²?
Find the altitude of a trapezium if the length of two bases are 4.6 cm and 2.4 cm respectively. The area of the trapezium is 42 cm²?
Explanation
Given:
Area = 42 cm²
Bases: a = 4.6 cm, b = 2.4 cm
Area formula: Area = (1/2) × (a + b) × h
42 = (1/2) × (4.6 + 2.4) × h
42 = (1/2) × 7 × h
42 = 3.5 × h
h = 42 / 3.5
h = 12
