the area of a rectangle = length x widthwe can rearrange this to give uslength of a rectangle = area/ width
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
Rectangle
The area of a rectangle with a width of 9 and length of 23 is 207 square units.
Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The area of rectangle is : 35.0
It's half the area of a rectangle
The area of rectangle is : 168.0
The area of rectangle is : 30.0
The area of rectangle is : 48.0
The area of rectangle is : 45.0
Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.
The area of rectangle is : 72.0
Nobody invented the area of a rectangle. A rectangle would have had an area even if human beings had never existed!
Area of a rectangle: a = l * w
