Question

The are of trapazeium is12 sq.
m. and it's height is 3m. ,find the sum of its parallel sides. ​

Answer 1

The sum of Parallel side is 8 metre

Answer 2

Answer:

8m

Step-by-step explanation:

Area of the given trapezium = 12m²

Formula for area of a trapezium = 1/2(a+b)h

• a and b are the parallel sides of the trapezium

• h is the height of the trapezium

Height of the given trapezium = 3m

according to the formula,

1/2(a+b)3 = 12m²

3/2(a+b) = 12m²

(a+b) = 12×2/3

(a+b) = 24/3

(a+b) = 8m

the sum of the parallel sides of the trapezium is 8m
