Question

if the area of a trapezium is 80cm and sum of the parallel sides is 20cm find its height​

Answer 1

Answer:

Height of trapezium is 8 cm.

Step-by-step explanation:

Given:

Area of trapezium = 80 sq. cm.

Sum of parallel sides = 20 cm.

As we know that,

Area of trapezium = (1/2)× sum of parallel sides × height

               80 = ( 1/2) × 20 × height

              (80 × 2) /20 = height

                160 / 20 = height

                8 = height

Answer 2

Answer:

The height of the trapezium will be 8 cm

Step-by-step explanation:

Here the area of trapezium is given to be 80 cm

Also, the sum of parallel sides is given to be 20 cm

We have to find the height of the trapezium

area of trapezium = (1/2) × sum of parallel sides × height

                        80 = (1/2) × 20 × height

                        80 = 10 × height

                  height = 80/10

                  height = 8 cm
