The formula for the area of a rectangle is a=

area of a rectangle is A = LW

Step-by-step explanation:

area equals length times width

example :

the Length of a rectangle is 3 feet

the Width of a rectangle is 4 feet

A=3 X 4

A= 12 ft.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
