Triangle formula A=bh

Question

Find the height of a triangle when A =18 in.² and B=9in? Explain?

Answer 1

A = bh/2

the area of a triangle is half the base times the height

18=9h/2

36=9h

h=36/9 = 4 inches

check the answer

A= bh/2

18=9(4)/2

18= 18

a square has A=bh

a triangle has area half that

draw a square, and then draw a triangle inside it with the same base and height. It has area half the square

just draw a diagonal across the square, that cuts the square into two triangles, each with half the area of the square
