Question

The ratio of parallel sides of a trapezium is 3:4. The distance between them is 4 cm. If area

of trapezium is 42 , find the lengths of parallel sides?​

Answer 1

Step-by-step explanation:

firstly, let the length of the parallel sides be 3x and 4x respectively.

we know that the area of trapezium =1/2* height * ( sum of two parallel sides)

A. T. Q;

42 CM = 1/2 *4* (3x+4x)

42 CM =2*(7x)

42cm/2= 7x

21cm =7x

21cm/7=x

3cm=x

so, the value of x is 3

Now, put the value of x

length of 1st parallel side be 3x=3*3=9cm

length of 2nd parallel side be 4x=4*3=12cm
