Question

the area of a trapezium is 12sq.m. if its height be 3m, find the sum of its parallel sied​

Answer 1

Answer:

8m^2

Step-by-step explanation:

we know

area=(sum of parallel sides)/2×height

ATQ,

12=(sum of parallel sides)/2×3

=>12/3×2=(sum of parallel sides)

=>8m^2=(sum of parallel sides)

Answer 2

Answer:

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

h is given as 3m

so sum of its parallel side means (a+b)

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

24 = (a+b) x 3

hence, (a+b) = 8
