<h3>
Answer: 64 cm^2</h3>
Reason:
The parallelogram has area of A = base*height = 10*7 = 70 cm^2
The white rectangle has area of B = base*height = 3*2 = 6 cm^2
The shaded region has area of A - B = 70 - 6 = 64 cm^2
If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
Step-by-step explanation:
since all 4 sides are equal in length, the figure is a square.
let the length of the square be lm.
529 = l x l
l = 23m
perimeter = 23 x 4 = 92m

Answer:
9 and 4 or D
Step-by-step explanation:
If you're not quite sure how to solve, let's find the answer by process of elimination.
If the area of a rectangle is 36 square inches, we can try option one.
7 * 6 = 42, not 36, so option A is incorrect.
Option two:
12 * 3 = 36 so option B is correct.
Option 3:
10 * 3 = 30 so option C is incorrect
Option 4:
9 * 4 = 36 so option D is correct
Now for perimeter:
9 + 4 + 9 + 4 = 18 + 8 = 26.
12 + 12 + 3 + 3 = 24 + 6 = 30
Thus, an answer of 9 and 4 is correct.
