The sum of the lengths of the two bases of a trapezoid is 22 cm and its area is 66 cm2.

ludmilkaskok [199]

Answer:

h = 6 cm

Step-by-step explanation:

Given that,

The area of a trapezoid, A = 66 cm²

The sum of the lengths of the two bases of a trapezoid is 22 cm.

We need to find the height of the trapezoid.

The area of a trapezium is given by :

$A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}$

Substitute the values,

$h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm$

So, the height of the trapezoid 6 cm.

$\frac{5x + 10}{x + 2} * \frac{2x}{4x - 10} = \frac{5(x) + 5(2)}{x + 2} * \frac{2x}{2(x) - 2(5)} = \frac{5(x + 2)}{x + 2} * \frac{2x}{2(x - 5)} = \frac{5}{1} * \frac{x}{x - 5} = \frac{5x}{x - 5}$

Step-by-step explanation:

1. 48 decide by 16 = 3 per min
