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:

26 is what percent of 78?

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
