the area of a trapezium is 34cm², the length of one of the parellel side is 10cm and its height is 4cm. Find the length of the other parallel side.
Answers
required question :
of a trapezium is 34 CM square the length of one of the parallel side is 10 cm and its height is 4 cm find the length of the other parallel side.
answer :
the height of the other parallel side is 7cm.
let's find out !!
given:
- area of trapezium = 34cm²
- length of one side of trapezium = 10cm
- height of trapezium = 4cm
using formula:
area of trapezium = ½ (a+b) ×h
so,
- =>> 34cm² = ½ (10+b) ×h
- =>> 34 × 2 ÷ 4 = 10 + b
- =>> 17 = 10+b
- =>> b = 10 -17
- =>> b = 7cm
hence the other side of trapezium is 7cm.

question : -
area of a trapezium shaped field is 48m² the distance between two parallel side is 15m and one of the parallel side is 20m. find the other parallel side.
solution :-
one of the parallel side of a trapezium is a = 20 metre , let another parallel side be b , height h = 15m.
the given area of trapezium = 480m².
area of a trapezium = 480m².
so,
- 480m² = ½ (a+b) ×h
- 480 ×2÷15 = 20 + b
- 64 = 20 + b
- b = 44m
hence the other parallel side of the trapezium is 44m.
Answer:
Given
- :⇒ The area of Ttrapezium = 34cm²
