Answer» Answer: 42.5 $unit^{2}$ Step-by-step EXPLANATION: area of trapezium = $\frac{h}{2}$ (a+b) where: h is height a & b are PARALLEL sides h = 5 a = 5 b = 12 $\frac{5}{2}$ ( 5 + 12 ) = 2.5 * 17 = 42.5 $unit^{2}$

Answer:

42.5 $unit^{2}$

Step-by-step EXPLANATION:

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

where:

h is height

a & b are PARALLEL sides

h = 5

a = 5

b = 12

$\frac{5}{2}$ ( 5 + 12 ) = 2.5 * 17 = 42.5 $unit^{2}$
