Since we know that dilation of a figure changes all sides of a figure by same factor.
Let us find out factor of dilation of our figure.
We will find side length QR of our quadrilateral QRST and its corresponding side QR' of quadrilateral Q'R'S'T'.
Let us find side length of Q'R'.
Let us compare both our side lengths to find factor of dilation,
Upon cross multiplication we will get,
We can see that Q'R' is of Q'R'. Therefore, our factor of dilation is .
Answer:
A=24 sq ft
P=20 ft
Step-by-step explanation:
To make this easier, separate the triangle and the rectangle. To find the area of the triangle multiply the bases and the height and then divide the answer by. So,
(6x4)/2
(24)/2
A=12
The base of the triangle is the same as the base on the rectangle. To get the perimeter, add the 3 side values up.
5+5+6
P=16
For the rectangle, to get the area, just multiply the base value and the height value. So,
(6x2)
A=12
To get the perimeter, add all the side values up. So,
6+6+2+2
P=12
Add the 5 sides of the pentagon up for the perimeter.
5+5+2+2+6
P=20
And finally, add the area of the triangle and the rectangle to get the area of the pentagon.
12+12
A=24
