The perpendicular height is 4 cm. Substitute the base and perpendicular height values into the formula. (7 × 4) ÷ 2 = 28 ÷ 2 = 14. The area of the triangle is therefore 14 cm² ...

A triangle consists of three sides (denoted as ‘a,’ ‘b,’ and ‘c’) and three angles (denoted as ‘A,’ ‘B,’ and ‘C’). The height of a triangle, sometimes referred to as the altitude, is the perpendicular ...

However, to calculate the area, you only need to know the length of its base (the longest side) and its height (the perpendicular distance from the base to the opposite vertex). Step 2: Acquire ...

The base and perpendicular height are at right angles. Showing that a parallelogram has the same area as a rectangle: Split the parallelogram into a right-angled triangle and a trapezium. Move the ...
