How do you find and triangles area? please step by step :]​

the area of a triangle is Base X Height / 2

Step-by-step explanation:

so basically the formula for finding the area of a triangle is the same as finding the area of a rectangle. base X height. except since a triangle is half a rectangle, you divide by 2. for example with this triangle:

the base is 30 and height is 21. you multiply 30 and 21, which gives you 630. then divide by 2, giving you, 315cm^2.

30 X 21 = 630 / 2 = 315 cm ^2

if you have any questions i can answer them.

Hope this helped!! :D

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: r there any options?
