The area of a triangle is 15 square inches, The
triangle's height is 5 inches. What is the length of the
base? Hint: A=1/2bh

Using the given equation for the area of a triangle, we can plug in what we know: 15 = (1/2)(b)(5)

Next, multiply both sides by 2 to get rid of the 1/2: 30 = 5b

Finally, divide both sides by 5 to get the length of the base: b = 6 inches

Hope this helps!! :)

6 inches

Step-by-step explanation:

Area of a triangle

= 1/2 x b x h

Given

Area = 15 square inches

Height h = 5 inches

Therefore

15 = 1/2 x b x 5

15 = 5b/2

Cross multiply

15 x 2 = 5b

30 = 5b

Divide both sides by 5

30/5 = 5b/5

6 = b

b = 6 inches
