What is the area of this figure?
2 answers:
This figure can be divided into two parts
1. A square of side 7 inches
2. A triangle of base 12 inches and height 7 inches
Lets calculate the individual areas and add them up
1. Area of the square = side × side
= 7×7 = 49 sq.inches
2. Area of the triangle = × base ×height
× 12 × 7
= 42 sq. inches
Lets add up the areas of the square and the triangle
= 49+42 = 91 in²

Answer: The image is attached.
Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case we know that the scale factor is:
Since:
It is an Enlargement.
You can identify that the vertices of the pre-image shown in the figure, are:
So you need to multiply the coordinates of those vertices by 4 in order to get the coordinates of the image;
Now you can draw it (The image is attached).
