formula for finding area of isosceles ∆

Answers

Answered by Anvi9876

area of triangle=1/2* length*breadth
if the length is not given we can use Heron's formula which is :

root of (s-a)(s-b)(s-c)

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

smartygame: heron's formula is root of s(s-a)(s-b)(s-c)

smartygame: and crrt ans is a× root of (4b^2 - a^2)/4

Anvi9876: hmm

smartygame: a =base ,b= equal sides

smartygame: all over , nice try

Anvi9876: thanks

To find the area of an isosceles Δ ...

using the length of the sides ...

label the length of each side, the base and the height if it's provided. then, use the equation area ,,,,,

= 1/2 base times height to find the area..

smartygame: this is the formula for finding area of triangle but the formula for finding area of isosceles triangle is a× root of (4b^2 - a^2)/4

Anvi9876: oh srry

Anvi9876: tried my best

smartygame: where a is base and b are equal sides
