To know the greatest common factor for the boys and girls row:

Obtain the greatest common factor of 27 and 18

Factors of :

27 : 1, 3, 9, 27

18 : 1, 2, 3, 6, 9, 18

Hence, the greatest factor common to both values (27 and 18) is 9

The area of a trapezium is 31.5 cm². If the parallel sides are of length 7.5 cm and 5.3 cm, calculate the perpendicular distance

spin [16.1K]

Answer:

<h3>The answer is 4.9cm</h3>

Step-by-step explanation:

To find the perpendicular distance between them that's the height we use the formula

$Area \: \: of \: \: a \: \: trapezium = \frac{1}{2} (a + b) \times h$

where

a and b are the parallel sides of the trapezium

h is the perpendicular distance

From the question

Area = 31.5cm²

a = 7.5 cm

b = 5.3 cm

Substituting the values into the above formula we have

$31 .5 = \frac{1}{2} (7.5 + 5.3) \times h$

$31.5 = \frac{1}{2} \times 12.8h$

$31.5 = 6.4h$

Divide both sides by 6.4

$h = \frac{31.5}{6.4}$

h = 4.921875

We have the final answer

<h3>h = 4.9cm</h3>

Hope this helps you
