Answer:
D. 135.37 in²
Step-by-step explanation:
We have that the gift paper consists of two circles and a square.
Thus, we will need to find the area of the circles and the square.
Now, as the diameter of the circle = 4 inches
So, the radius of the circle = = 2 inches
Since, the area of a circle =
This implies that area of the two circles =
i.e. Area of the circles =
i.e. Area of the circles =
i.e. Area of the two circles = 25.133 in²
Further, one side of the square = 10.5 inches
Thus, the area of the square =
i.e. Area of the square =
i.e. Area of the square = 110.25 in²
So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².
Hence, the amount of paper used by Angela is 135.37 in².
Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to
sq. units.
