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.
