A watercolor painting is 16 in long by 11 inch wide ramon makes a border around a watercolor painting by making a mat that adds 1 inch to each side of the length and the width. What is the area of the mat?

234 Square Inches

Step-by-step explanation:

Length of the Painting=16 in

Width of the Painting= 11 inch

Since the mat adds 1 inch to each side of the length and the width.

Therefore:

Length of the mat=16+1+1=18 Inch

Width of the Mat=11+1+1=13 Inch

Area of the Mat= Length X Width

=18X13=234 Square Inches

Step-by-step explanation:

The watercolor painting is rectangular. It has a length of 16 inches and a width of 11 inches.

The formula for determining the area of a rectangle is expressed as

Area = length × width

If a border whose width is 1 inch is added to the length and width of the watercolor painting to make a mat, then the length of the mat is

16 + 1 + 1 = 18 inches

The width of the mat is

11 + 1 + 1 = 13 inches

Area if mat = 18 × 13 = 234 square inches
