Area = length * height. A = 20cm * 12cm A = 240 cm2

If you mean a rectangle, just multiply the length times the height. If (for example) length and height are in centimeters, then the area is in square centimeters. Similar for other units.

884 cm squared Area of a rectangle is length times width, so it is simply 26 cm x 34 cm.

Area in square units: length times perpendicular height

Area = length * height. A = 20cm * 12cm A = 240 cm2

Area of a rectangle can be determined by Length multiplied by Height. 3 x 10 = 30, so the area of the rectangle is 30 cm2

If you mean a rectangle, just multiply the length times the height. If (for example) length and height are in centimeters, then the area is in square centimeters. Similar for other units.

The area of a rectangle is simply length x width. If the measurements are in centimeters, then the area will come out in square centimeters.

In a rectangle, the area is calculated by multiplying length x width. If (for example) both length and width are in centimeters, the area will be in square centimeters.

Height = Area divided by Length

Diagonal = 17 cm and height = 8 cm so Length = sqrt[172 - 82] = sqrt(225) = 15 cm Then area = length*height = 15*8 = 120 cm2

A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude."

There is no "height" of a rectangle, unless it's a rectangular prism. Do you mean the length? If you have the area of the rectangle, the equation should be:A= L x WPlug in the area and the length and solve for the width, or plug in the area the width of the rectangle, and solve for the length.
