Question

find the altitude of a trapezium the sum of the length of whose base is 8.5 cm and whose area is 34cm sq​

Answer 1

Answer:

5

This is ur answer

Answer 2

Answer:

8cm

Step-by-step explanation:

Let a and b are two parallel sides of a trapezium .

Given ,

a+b = 8.5 cm

Area of trapezium = 1/2*Sum of parallel sides * Altitude

Area of trapezium = 1/2*(a+b)*Altitude

34= 1/2*8.5*Altitude

34=1/2*17/2*Altitude (8.5=85/10=17/2)

34=17/4*Altitude

(34*4)/17=Altitude

136/17= Altitude

8 cm = Altitude
