The height of trapezium is 6.01cm

Step-by-step explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is the height. Next, you have to substitute the following values into the formula :

$area = \frac{1}{2} \times (a + b) \times h$

$let \: area = 42.7 \\ let \: a = 9.2 \\ let \: b = 5$

$42.7 = \frac{1}{2} \times (9.2 + 5) \times h$

$42.7 = \frac{1}{2} \times 14.2 \times h$

$42.7 = 7.1 \times h$

$h = 42.7 \div 7.1$

$h = 6.01cm \: (3s.f)$

Test :

Let a = 9.2,

Let b = 5,

Let h = 6.01,

$area = \frac{1}{2} \times (9.1 + 5) \times 6.01$

$area = \frac{1}{2} \times 85.342$

$area = 42.7 {cm}^{2} \: (proven)$
