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

Hope this helps you

Which description corresponds to the relationship shown in the table?

Sladkaya [172]

Answer:

Step-by-step explanation:

7*5 = 35+15 = 50

10*70 = 70 +14 = 85

15*7 = 105 +15 = 120

20*7 = 140+15 = 155

B]8.50*5 = 42.5

C]10*5 = 50

10*10 = 100

D] = 8*5 = 40 +10 = 50

10*8 = 80+10 = 90
