the area of a triangle is 40cm2. the height of it is h cm. what is the lenght of its base?
since
(1/2)bh = 40
bh = 80
b = 80/h cm
To find the length of the base of a triangle given its area and height, we can use the formula for the area of a triangle:
Area = (1/2) * base * height
In this case, we have the area as 40 cm^2 and the height as 'h' cm. We need to find the length of the base, represented as 'b' cm.
Using the formula, we can rewrite it as:
40 = (1/2) * b * h
To solve for 'b', we can rearrange the formula:
b = (2 * Area) / height
Substituting the given values:
b = (2 * 40) / h
Simplifying the equation further:
b = 80 / h
Therefore, the length of the base is 80 divided by the height in centimeters.
