Question

“Hiii dear"
The area of a trapezium is 400 cm2, the distance between the parallel sides is 16 cm. If one of the parallel sides is 20 cm, find the length of the other side.

Answer 1

Answer: h≈22.22cm

Step-by-step explanation:

Using the formula

A= a+b

           h

    2      

Solving for h

h=2   A                 400

     _____ = 2.     ____  = 22.2222 cm

     a+b                 16+20

hope tis helps u

Answer 2

Answer:

The length of other side of trapezium is 30 cm.

Step-by-step-explanation:

We have given that,

• Area of trapezium = 400 cm²
• Distance between parallel sides ( Height ) = 16 cm
• Length of one parallel side = 20 cm

We have to find the length of other parallel side.

We know that,

Area of trapezium = ( Sum of lengths of parallel sides ) * Height / 2

⇒ 400 = ( Length of side 1 + Length of side 2 ) * 16 / 2

⇒ 400 * 2 = ( 20 + Length of side 2 ) * 16

⇒ 800 = ( Length of side 2 + 20 ) * 16

⇒ Length of side 2 + 20 = 800 ÷ 16

⇒ Length of side 2 + 20 = 50

⇒ Length of side 2 = 50 - 20

⇒ Length of side 2 = 30 cm

∴ The length of other side of trapezium is 30 cm.
