To find the area of the letter D, we can decompose it into simple shapes.
The letter D can be broken down into a rectangle and a semicircle.
The rectangle has dimensions of 6 cm by 2.1 cm (height and width of the straight part of the D).
The semicircle has a radius of 0.5 cm (radius of the curved part of the D).
The area of the rectangle is 6 cm * 2.1 cm = 12.6 cm^2
The area of the semicircle is 0.5 * pi * (0.5)^2 = 0.393 cm^2
Therefore, the total area that needs to be covered in gold leaf is 12.6 cm^2 + 0.393 cm^2 = 12.993 cm^2
So, the artist will need 12.993 square centimeters of gold leaf.
An artist wants to cover in gold leaf a card with the initial letter shown. Decompose the letter into simple shapes to find the area. How many square centimeters of gold leaf will the artist need? Do not round your answer. 6, 0.8, 2.1, 0.5, 0.8 Letter D
