Given:
The base of the triangle = 8.6 yd
The height of the triangle = 10.9 yd
To find the area of the triangle.
Formula
The area of a triangle with b as base and h as height is
Now,
Taking, b= 8.6 and h = 10.9 we get,
sq yd
or, sq yd
Hence,
The area of the given triangle is 46.87 sq yd.
<em><u>Percent value of A with respect to Percent value of B is,</u></em>
In the question,
Let us say the value of the Baseball card A and B initially is = 100x
So, for Baseball card A in first 5 years percent increase = 20%
So,
Value after 5 years = 100x + 20% of 100x = 120x
<u>After 5 more years,</u>
Percent decrease = 50%
So,
<u>Value at the end of 10 years = 120x - 50% of 120x = 60x</u>
Now,
For Baseball card B, Percent increase in 10 years = 100%
So,
<u>Value of card B = 100x + 100% of 100x = 200x</u>
So,
<em><u>Percent value of A with respect to Percent value of B is,</u></em>
