Question

A triangle has an area of 63 square inches. if the height s 9 inches. what is the length of the base

Answer 1

A=b*h/2
You will do it reversed
So you will do 63*2
Which is 126 and then you will do 126/9
Which is 14
The length is 14.

Check your work
A=b*h/2
63=9*14/2
63=126/2
63=63

Answer 2

14 = b or b = 14

Explanation:

Area of a triangle: 1/2*b*h

Area = 1/2*b*h

63 = 1/2*b*9

63 = 9/2b

2(63 = 9/2b)

126 = 9b

/9 /9

14 = b or b = 14

Check:

63 = 1/2*b*9

63 = 1/2*14*9

63 = 7 * 9

63 = 63

Hope this helps!
