The area of a triangle is 54.5cm. What is the triangle's base if the height is 4 cm?

A = bh/2

54.5 = 4b/2

109 = 4b

27.25 = b

To find the base of a triangle given the area and height, you can use the formula:

Area of triangle = (1/2) * base * height

In this case, the area is 54.5 cm² and the height is 4 cm. Let's substitute these values into the formula and solve for the base:

54.5 cm² = (1/2) * base * 4 cm

Now, let's isolate the base by multiplying both sides of the equation by 2:

2 * 54.5 cm² = base * 4 cm

109 cm² = base * 4 cm

To find the base, divide both sides of the equation by 4:

base = 109 cm² / 4 cm

base = 27.25 cm

Therefore, the base of the triangle is 27.25 cm.

To find the base of the triangle, you can use the formula for the area of a triangle:

Area = (base * height) / 2.

Here, the area is given as 54.5 cm and the height is 4 cm. Plugging those values into the formula, you get:

54.5 = (base * 4) / 2.

To solve for the base, we can rearrange the equation:

54.5 * 2 = base * 4.

109 = base * 4.

Now, divide both sides by 4 to isolate the base:

109 / 4 = base.

So, the base of the triangle is 27.25 cm.
