Question

How to find The Area of Qardiletrals . spamming Allowed.​

Answer 1

꧁༺༒ANSWER༒༻꧂

If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.

Answer 2

For a regular quadrilateral:-

Use formulae like,

• area of square = side²
• area of rectangle = length · breadth, etc.

For an irregular quadrilateral:-

Break it into a number of triangles (draw a diagonal first for that purpose) and then find the area of the triangles separately by the formula (½ · base · height) and sum them up.

{Q. for you: Derive the area of a Trapezium. Hint: Draw a diagonal and find their areas and add them.}

Basic formula to find the area of any quadrilateral:-

Area = $d \times p$

where, d = diagonal and p = perpendicular to the diagonal from the corresponding vertex.
