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
1000 because 9 round up =10 which means you need to round up again and again so it equals 1000
Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
