Question

The area of a triangle A is given as A =1/2 bh, where b is the base an h = height. (a) find h if A =30 and b=10

Answer 1

h = 6

Explanation:

Substitute the given to its corresponding places.

30 =
`(1(10)h)/(2)`

30 = 10h/2

Multiply both sides by two to remove the denominator.

2 [30 = 10h/2] 2

60 = 10h

Divide both sides by 10 to isolate h.

h = 6

To check, substitute everything to the original equation:

A =
`(1(10)(6))/(2)`

A = 30 !
