### Given :-

• Sides are 3 cm and 7 cm.
• Height between them is 4 cm.

### To Find :-

• The area of trapezium.

### Step-by-Step-Explaination :-

As we know that :-

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

Putting the respective value,

Area of trapezium = 1/2 × ( 3 + 7 ) × 4

Area of trapezium = 1/2 × 10 × 4

Area of trapezium = 5 × 4

Area of trapezium = 20

### Therefore,

The area of trapezium is 20 cm².

### Hence,

Option b) 20 cm² is correct option.
