3 <p>The base area of a trapezium refers to the area of the flat surface, which is a 2-dimensional shape. A trapezium (or trapezoid) is a quadrilateral with at least one pair of parallel sides.</p>

4 <h2>What is the Base Area of a Trapezium?</h2>

5 <p>The<a>base</a>area<a>of</a>a trapezium is simply the area enclosed by its four sides.</p>

6 <p>A trapezium is a 2-dimensional shape with one pair of parallel sides called bases and two non-parallel sides called legs.</p>

7 <p>The area of a trapezium is the total space enclosed by these sides.</p>

8 <h2>What is the Base Area of a Trapezium Formula?</h2>

9 <p>The<a>formula</a>for the area of a trapezium is given by: Area = 1/2 × (Base1 + Base2) × Height</p>

10 <p>In this formula, Base1 and Base2 are the lengths of the parallel sides, and the Height is the perpendicular distance between these sides.</p>

11 <h2>How to Find the Base Area of a Trapezium?</h2>

12 <p>The base area of a trapezium can be found using the formula: Area = 1/2 × (Base1 + Base2) × Height.</p>

13 <p>This formula can be used to find the base area by following these steps:</p>

14 <p><strong>Step 1:</strong>First, determine the lengths of the two parallel sides (Base1 and Base2) and the height of the trapezium.</p>

15 <p><strong>Step 2:</strong>Use the formula Area = 1/2 × (Base1 + Base2) × Height to find the area.</p>

16 <p><strong>Step 3:</strong>Write the answer in<a>square</a>units.</p>

17 <p>For example, if the trapezium has bases of 5 cm and 7 cm, and the height is 4 cm, find the base area:</p>

18 <p>Area = 1/2 × (5 + 7) × 4 = 1/2 × 12 × 4 = 24 cm²</p>
