Question

6. The original length, L, and original width, W. of a rectangular garden are BOTH increased by 3 feet each.

Write an expression to show
A. the AREA of the NEW rectangle
B. the PERIMETER of the NEW rectangle​

Answer 1

Step-by-step 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)
