Area and Circumference Formula of Rectangle

Rectangular Properties

These are the properties of the rectangle, among which are:

The opposite sides are parallel and the same length.
The four right angles ∠a = ∠b = ∠c = ∠d.
The two diagonals are the same length AC = BD (diagonal).
It has two axes of symmetry.

Formula of Rectangle Area

A = l x w

Information:
A = Area
l = long
w = width

Example Question of Rectangle Area

What is the area of a rectangle that has a length of 3cm and a width of 2cm?

Answer:
l = 3cm
w = 2cm

A = p x l
A = 3cm x 2cm
A = 6cm²

So the area of a rectangle that has a length of 3cm and a width of 2cm is 6cm²

Formula of Circumference Rectangle

C = 2(P + l)

Information:
C = Circumference
l = Length
w = Width

Example Question of Circumference Rectangle

What is the circumference of a rectangle that has a length of 3cm and an area of 2cm?

Answer:
l = 3cm
W = 2cm

C = 2(P + l)
C = 2(3cm + 2cm)
C = 2(5cm)
C = 10cm

So the circumference of a square that has a length of 3cm and a width of 2cm is 10cm.
