Question

Maths--- Grade 8----Trapezium

Answer 1

area of trapezium =9450sq.m
Let one parallel side be 'x',then A.T.Q, the other parallel side be '2x'
The distance between two parallel=84m
area of trapezium =h(a+b)/2
9450=84(x+2x)/2
9450*2=84(3x)
18900=84(3x)
18900/84=3x
225=3x
x=225/3
x=75
Therefore, the length of the longer side of the parallel side=2x=2*75=150m


HOPE IT HELPS.

Answer 2

Answer:

The length of longer side is 150 m

Step-by-step explanation:

Let one side be a=x

Another side be b=2x

The height is given as 84m

The area is $9450^{2}$

1/2 (a+b)h=$9450m^{2$

3x(84)=18900

x=18900/3×84

x=75

So the length of longer side is 150 m
