Area of a rectangle: a = l * w
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
Multiply the base by the height !
Length x Width LxW
I beleve that is the formula for finding the area of a rectangle or squareLength*Width equals area for rectangles. LxW=Area of a rectangle.
Area of a rectangle: a = l * w
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
A = lw Area of a rectangle = length times width
base times height = area
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
Multiply the base by the height !
pi * r * (r + sqrt(r^2 + h^2))
Squares are rectangles so the formula for area will stay the same.
Length x Width LxW
I beleve that is the formula for finding the area of a rectangle or squareLength*Width equals area for rectangles. LxW=Area of a rectangle.
The formula for finding the surface area of a rectangle is length x width. 3.14 is the value for pi and is used for circles, cylinders, and spheres and has nothing to do with rectangles.
The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c). The formula for theSurface Area of a Rectangular Prism = 2ab + 2bc + 2ac
