Question

If the side

of

an equilateral triangle is 8cm then area of the triangle will be
16√3cm​

Answer 1

Step-by-step explanation:

half into b into h is a area

we know that the 3 sides of an equilateral triangle is equal

so b is equal to 8

to find the height

first divide the triangle in two halves

so formed a right angled triangle

using Pythogorem theorem u can find the height

A square=h square -b square

8 square -4square it was divided =

=64-16

=48

A = root of 48

A=6.9....

A=1/2 ×8×6.9

= 27.6cm square
