Question

the area of trapezium is 12sq.m.If its height be 3m,find the sum of its parallel side

Answer 1

Area of trapezium = 12 m² (Given)

height = 3 m (Given)

.

Area of trapezium = 1/2 (a + b) h where a + b is the sum of the parallel side.

.

Plugged in the known variables and find a + b:

1/2 ( a + b ) (3) = 12

divide by 3 on both sides:

1/2 ( a + b) = 4

multiply by 2:

a + b = 4

.

Answer: The sum of its parallel sides is 4 m
