Given :
Area of trapezium = 850 sq.m
Length of one of the parallel sides = 64 cm
Perpendicular distance between the parallel sides = 17 cm
To Find :
The length of the other parallel side
Solution :
Area of a trapezium is given by ,
Here ,
a and b are length of parallel sides
h is distance between the parallel sides
We have ,
a = 64 cm
A = 850 sq.m
d = 17 cm
Substituting the values ;
Hence ,
The length of the other parallel side is 36 cm

Answer:
- Other parallel side of trapezium is 36 cm.
Step-by-step explanation:
Given :-
- Area of trapezium is 850 cm².
- One parallel side is 64 cm.
- Perpendicular distance between the parallel sides is 17 cm.
To find :-
- Length of other parallel side.
Solution :-
Let, Other parallel side of trapezium be x.
We know,
Area of parallelogram = (a + b)/2 × h
Where,
- a and b are parallel sides of trapezium.
- h is height or we can say distance between parallel sides.
Put all values in formula:
⇒850 = (a + b)/2 × h
⇒850 = (65 + x)/2 × 17
⇒850/17 = (65 + x)/2
⇒50 = (65 + x)/2
⇒50 × 2 = 65 + x
⇒100 = 65 + x
⇒100 - 65 = x
⇒x = 36
We take,
Other parallel side be x.
So,
Other parallel side of trapezium is 36 cm.
