The total area of the figure is 141 in^2.
To find the area of this figure you need to separate it into different sections.
First to find the area of the triangle on the left is multiple 8 by 3, giving the area of 24.
Second find the area of the rectangular shape towards the left, and ignore the triangle ends on both sides for now. To find the area of the rectangle multiply 10 by 9.
Lastly, to find the area of both triangles on both ends is to multiply 9 by 3. The three is found by subtracting 10 from 16 and dividing it by two.
Adding all the areas together gives you the answer = 141 in^2
Answer:
The area of silver charm is 33.75 square mm.
Step-by-step explanation:
We are given the following in the question:
The silver and golden charms are similar isosceles triangles.
Gold charms:
Base = 9 mm
Area = 15 square mm
Silver charm:
Base = 9 mm
Property of similar triangles:
- If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.
Using this property we can write:
Thus, the area of silver charm is 33.75 square mm.
