Question

The area of the trapezium is 63cm and the top is 6cm and the bottom is 12cm what’s the height

Answer 1

Answer:

height = 7 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated using the formula

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

where h is the height and a, b the parallel bases

here a = 6, b = 12 and A = 63, hence

$\frac{1}{2}$ × h × (6 + 12) = 63

$\frac{1}{2}$ h × 18 = 63

9h = 63 ( divide both sides by 9 )

h = 7
