Answer:
Explanation:
A rectangle is a two-dimensional quadrilateral.
The area is given as:
Area of a rectangle = length x width
Perimeter = 2(L+ W)
where L is the length and W is the width
Condition:
If L and W are increased by 3 feet each;
New length = L + 3
New width = W + 3
Area of new rectangle;
Area = (L + 3) x (W + 3)
= LW + 3L + 3W + 9
Perimeter of new rectangle;
Perimeter = 2(L+3 + W + 3)
= 2(L+W +6)
