What is area?
The measurement that indicates the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. The "space encompassed inside the perimeter or the boundary" of the specified form is what is referred to as a shape's area. Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.
Here,
Let w be the width and l be the length of the rectangle,
The area of rectangle= 63 feet²
area=w*l
l=w+2
w(w+2)=63
w²+2w=63
w²+2w-63=0
w²+9w-7w-63=0
w(w+9)-7(w+9)=0
(w-7)(w+9)=0
w=-9, 7
width=7 feet
length= 9 feet
