Question

the area of a Trapezium is 12 square metre if its height be 3 metre find the sum of its parallel sides

Answer 1

area of trapezium=1/2(a+b) h
12=1/2×(a+b)3
(a+b)=12×2÷3
(a+b)=8

Answer 2

area of trapezium=12m²
height=3m
area=½(sum of parallel sides)*height
12=½(sum of parallel sidea)*3
12*2/3=sum of parallel sides
8m=sum of parallel sides
