Question

if the parallel sides of a trapezium are 16 cm and 14 cm and distance between the parallel side is 8 cm then its area is​

Answer 1

Answer:

x =3cm

Step-by-step explanation:

Here length of one parallel side of the trapezium = 5cm let the other side be x cm

Area of trapezium =16 cm square and height of the trapezium = 4cm

As we know area of trapezium =1/2(sum of parallel sides)

Or 1/2(5+x )4 = 16 {by putting the values}

Or 1/2(20+4x) = 16

Or (10+2x) = 16

Or 10+2x = 16

Or 2x = 16-10

Or 2x=6

Or x = 6/2

Therefore x =3cm

THEREFORE THE LENGTH OF OTHER PARALLEL SIDE=3 cm

Answer 2

Answer :

• Area of trapezium is 120cm²

Given :

• The parallel sides of a trapezium are 16cm and 14cm
• Distance between the parallel side is 8cm

To find :

• Area

Solution :

As we know that,

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

Given,

• Parallel sides are 16cm and 14cm
• Height is 8cm

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

》1/2 × (16 + 14) × 8

》1/2 × 30 × 8

》15 × 8

》120 cm²

Hence, Area of trapezium is 120cm²
