Question

The parallel side of a trapezium measure 12cm ​

Answer 1

Answer: 240 cm²

Step-by-step explanation:

a = 12 cm

b = 20 cm

h = 15 cm

area of trapezium = $\frac{a+b}{2}$ × h

                              = $\frac{12 + 20}{2}$ × 15

                              = $\frac{32}{2}$ × 15

                              = 16 × 15

                              = 240 cm²
