Question

the area of a Trapezium is 34 CM square and the length of its parallel side is 10.4 cm and its height is 4 cm find the length of the Other parallel side

Answer 1

use the formula: 1/2 (sum of parallel sides)height

Answer 2

Answer:

6.6 cm

Step-by-step explanation:

Define x:

Let the unknown parallel side be x

Solve x:

Area of the trapezium = 1/2 ( a + b) x h

1/2 (10.4 + x ) (4)  = 34

20.8 + 2x = 34

2x = 13.2

x = 6.6 cm

Answer: The other parallel side is 6.6 cm
