Option 1: 1.4
Option 2: 0.014
Option 3: 140
Option 4: 0.14
Correct Answer: 0.014
Solution :
Given: The two parallel sides of a trapezium are 27 cm and 13 cm.
Height = 7 cm
Area of a trapezium
= $\frac{1}{2}$ × Sum of two parallel sides × Height
= $\frac{1}{2}$ × (27 + 13) × 7
= $\frac{1}{2}$ × (40) × 7
= 140 cm

= $\frac{140}{10000}$ m
