The length of the rectangle is found as 7 feet.
Explain the properties of rectangle?
- It consists of four vertices and four sides.
- Every vertex has a 90 degree angle.
- A quadrilateral is a rectangle.
- The opposing sides are level and parallel to one another.
- 90 degrees is the angle of each interior.
- 360 degrees is the total of all interior angles.
For the stated question;
Let the length and the width of the rectangle be 'L' and 'B'.
Then, width is given as;
W = L-2
Area = 35 square feet
A = LW = 35
Put the value of W
L(L-2) = 35
L² -2L - 35 = 0
L² -2L - 35 =0
(L-7)(L+5) = 0
L > 0 so, L=7 is solution
Thus, the length of the rectangle is found as 7 feet.
