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

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!
