leanth times width
A trapezoid has 2 inner triangles and so work out the area of each triangle then add them together. Alternatively use the formula for area of a trapezoid which is:- 0.5*(sum of parallel sides)*height
Use Heron's Formula
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
To find the area of a book cover in metric units, the most appropriate unit to use would be centimeters. The formula for finding the area of a book cover would be: length x width.
The volume of the rectangle is of no use to you, since the volume of every rectangleis zero. What you need to know is the rectangle's area and length.You're supposed to know that the area is the product of (length) times (height).So if you know the area and one of the dimensions, you can use that formula tofind the other dimension.
Area of a trapezoid = (1/2) x (height) x (length of the base + length of the top)
A trapezoid has 2 inner triangles and so work out the area of each triangle then add them together. Alternatively use the formula for area of a trapezoid which is:- 0.5*(sum of parallel sides)*height
The formula for the area of a trapezoid is a combination of the formulas for the areas of a triangle and a rectangle. It can be seen as two congruent triangles placed together to form a parallelogram. So, the formula for the area of a parallelogram is a generalization of the formula for the area of a trapezoid.
They both use perpendicular height and are in square units. Area of a trapezoid = 0.5*(sum of parallel sides)*perpendicular height Area of a parallelogram = base*perpendicular height
To find the area of a trapezoid you have to use the equations: [Height divided by 2] x [base1+base2] and the answer you get is the area of the trapezoid.
You always use square units when measuring area.
You use pi ( 3.14)To find the area of a circle you use this calculationpi x r x r.
To find the height of a trapezoid with the given area and bases, you can use the formula for the area of a trapezoid: A = (1/2)(b1 + b2)(h), where A is the area, b1 and b2 are the bases, and h is the height. Rearranging the formula, we can calculate the height as: h = 2A / (b1 + b2). Therefore, the height of the given trapezoid is: h = 2(9) / (2.4 + 3.6) = 2.25 units.
If the base is a rectangle, use the formula for the area of a rectangle.
Use Heron's Formula
To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
