The area of a triangle is 40cm2. if its height is 5cm, what is its base?
a=bh/2
40=b(5)/2
80=b(5)
16=b
16 is the height of the triangle
Jdawg has a typo.
16 is the base of the triangle.
To find the base of the triangle, we can use the formula for the area of a triangle, which is given by:
Area = 1/2 * base * height
In this case, the area of the triangle is given as 40 cm^2, and the height is given as 5 cm. Plugging these values into the formula, we get:
40 cm^2 = 1/2 * base * 5 cm
To solve for the base, we can rearrange the equation by multiplying both sides by 2 and then dividing both sides by 5:
40 cm^2 * 2 = base * 5 cm
80 cm^2 = base * 5 cm
Next, we can divide both sides of the equation by 5 to isolate the base:
80 cm^2 / 5 cm = base
Simplifying this further, we have:
16 cm = base
Therefore, the base of the triangle is 16 cm.
