Respuesta :

Esther

Answer:

14 = b or b = 14

Step-by-step 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!

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
