Question

If the area of a trapezium is 28 m², and two parallel sides are 8 m and 60 dm
respectively, find the altitude.
Find the height of a trapezium whose area is 1,080 cm2 and lengths of its parallel
sides are 55.6 cm and 34.4 cm..
The area of a trapezium is 12 sq. m. If its height be 3 m, find the sum of its
parallel sides.​

Answer 1

Step-by-step explanation:

find: height

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

1080cm=1/2h(55.6+34.4)

1080cm=1/2h(90)

1080cm=90h/2

1080cm×2=90h

2160/90=h

24=h

12=3/2(2x)

12×2/3=2x

8=2x

4=x

sum of two parallel sides=8
