How do you do base times height divided by 2?

How do you do base times height divided by 2?

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

What is the formula for base times height?

The area of a rectangle is base × height, alternatively written as length × width.

What formula is half base times height?

The area of a triangle is half its base times its height: A=0.5bh.

What formula is V BH?

The volume of a cylinder can be determined using the formula V = Bh where B is the area of the base of the cylinder and h is the height.

What is a BH formula?

The formula for the area of a parallelogram is: A = bh, where b is the length of the base and h is the length of the height. The formula for the area of a rectangle is: A = lw, where l is the length of the length and w is the length of the width of the rectangle.

Why is the area half of BH?

Why is the Area “Half of bh”? THEN the whole area is bh, which is for both triangles, so just one is ½ × bh.

What is a 1/2 BH?

A diagonal of a rectangle separates the rectangle into two congruent triangles. The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

What is V pi * r 2 * H?

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .

What is area multiplication?

Multiplying by a 1-digit number using area models Show the problem as the area of a rectangle, and then break that rectangle into smaller chunks for easier solving. This method is also known as box multiplication.

How do you solve for B in BH 2?

Algebra Examples Cancel the common factor of 2 . Cancel the common factor. Divide each term by h and simplify. Divide each term in bh=2A b h = 2 A by h h .
