The area of a triangle is 135 square inches. If the height is 15 inches, what is the length of the base?
b= 18 inches
Thanks for the help
a = bh/2
135 = b*15/2
...
A = 1/2 * b * h
135 = (1/2)b * 15
135 = 7.5b
135/7.5 = b
? = b
Right.
You're welcome.
Thanks
To find the length of the base of a triangle, you can use the formula for the area of a triangle:
Area = (1/2) * base * height
Given that the area of the triangle is 135 square inches and the height is 15 inches, we can substitute these values into the formula to solve for the length of the base.
135 = (1/2) * base * 15
To solve for the length of the base, we can simplify the equation as follows:
135 = (1/2) * 15 * base
135 = 7.5 * base
To isolate the base, divide both sides of the equation by 7.5:
base = 135 / 7.5
base = 18
Therefore, the length of the base of the triangle is 18 inches.
