Answer:
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
Answer:
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
