Answer:
19 square units
Step-by-step explanation:
There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes. For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.
Rectangle: would be from -3 to 3 (6) and -2 to 4 (6). 6x6=36
The four missing triangles:
AB = 1/2(3)(2)=3
BC = 1/2(2)(4)=4
CD = 1/2(2)(4)=4
DA = 1/2(4)(3)=6
6+4+4+3=17
36-17=19
Answer:
5b
Step-by-step explanation:

(a) The Rectangles are similar because all angles of all rectangles are equal to 90°. Then, the corresponding sides have the equivalent ratio equal to k.
(b) The perimeter of the rectangle is the sum of the measurements of all sides. Such that for Rectangle 1, it should be.
Perimeter (Rectangle 1) = 2x + 2y
Then for rectangle 2,
Perimeter (Rectangle 2) = 2kx + 2ky = k (2x + 2y)
= k(Perimeter of rectangle 1)
c. Area of rectangle is the product of the lengths of two sides, (x)(y). For Rectangle 2, that would be (kx)(ky) = k²xy
