Question

If the area of a trapezium is 28m²,and two parallel sides are 8m and 60dm respectively,find the altitude.​

Answer 1

Answer:

h=4m

Step-by-step explanation:

area of trapezium=1/2*sum of parallel sides*height

given,

area=28m sq.

parallel sides=8m and 60/10m

28=1/2*(8+6)*h

56=14h

h=56/14

h=4m

Answer 2

Answer:

Height or altitude of the trapizium is 4m.

Step-by-step explanation:

We have given that-

Area of trapizium = 28m²

Parallel sides = 60dm and 8m

we'll covert the 60 dm in m first.

So, 60dm = 6m

_______________________

As we know,

area of trapizium = ½ × h × (sum of the parallel sides)

So,

A.T.q -

»» ½ × (8+6)h = 28

»» ½ × 14h = 28

»» 7h = 28

»» h = 4
