Question

what is the formula of quadrilateral​

Answer 1

Answer:

ok

Step-by-step explanation:

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.

it is area

The formula is a + b + c+ d = perimeter. For example, suppose that a quadrilateral has sides with lengths of 1, 5, 3 and 4 inches. The perimeter equals 1 + 5 + 3 + 4 or 13 inches

1. it is formula of perimeter .

Answer 2

Answer:

area= 1/2×d×(h1+h2) {h= height, d=diagonal}

perimeter= sum of all side
