The length of a rectangle is 3 cm greater than the width.
If each dimension is increased by 2 cm, the area is increased by 26 cm².
Find the original dimension of the rectangle.
Let = width of the rectangle.
Then = length of the rectangle.
The area of this rectangle is: . m².
If each dimension is increased by 2 cm,
. . the new width is: ,
. . the new length is:
The area of the new triangle is: . m².
We're told that the new area is 26 m² more than the original area.
There is our equation! . . . . .
