Question

what is area of triangle?​

Answer 1

Answer:

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

Answer 2

Answer:

Area of triangle when height amd base are given is=1/2 ×base × height

Step-by-step explanation:

or

Heron's Formula=

Area = √s(s-a)(s-b)(s-c)

where s is the semi perimeter and a,b,c are sides of triangle.

To find semi perimeter add the sides and divide it by 2.

(a+b+c)/2
