Best Answer

Let the given area is 10cm.

Base of the triangle is 4 cm.

altitude of triangle=?

Area= 1/2 x Base x altitude

10= 1/2 x 4x altitude

10=2 x altitude

10/2= altitude

5= altitude

Hence, altitude of the triangle is 5 cm.

1/2*base*perpendicular height or altitude in square units

The altitude of a triangle is measured perpindicular to its base.

It depends on what other information you have. Knowing the lengths of two sides of a triangle is not enough to calculate the third. You need to have some further information: and angle, the area, the length of an altitude or a median.

is the altitude of a triangle

Yes its perpendicular height or altitude is sometimes calculated out side the triangle depending on its shape.

the formula for the area of a triangle is A=1/2(bh) Where A is area, b is the base, and h is the height(or altitude).

The triangle's altitude is 8.7 (8.66025) cm.

The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.

Yes

It is the triangle's perpendicular altitude
