Answer:
21 units^2
Step-by-step explanation:
Dimensions of rectangle are 3 by 6 units; therefore the area is 18 units^2.
Dimensions of triangle: base is 3 and height is 2; therefore the area of this triangle is (1/2)(base)(height) = (1/2)(3)(2) = 3 units^2
The total area of this figure is (18 + 3) units^2, or 21 units^2

<u>Diagonals are perpendicular. Side length of the rhombus:</u>
<u>Perimeter:</u>
The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
Answer:
A total of 4 beads can fit on a string that is 8 inches long.
