Answer:
<em>10a + 10b / 9x - 9y = 2 / 3</em>
Step-by-step explanation:
As we can see;
10 * ( a + b ) / 9 * ( x - y ) ⇒ 10a + 10b / 9x - 9y
This concludes that the top part of this equation is multiplied by 10 and the bottom by 9. To derive the solution, let us do the same with 3 / 5;
10a + 10b / 9x - 9y = 3 * 10 / 5 * 9
And simplify, to recieve;
10a + 10b / 9x - 9y = 30 / 45 = 6 / 9 = 2 / 3,
<em>Answer: 10a + 10b / 9x - 9y = 2 / 3</em>
Area of base of Triangle
= ½(15)(5)
= 37½ units²
Area of sides of Triangles
= (15 × 9) + ½(17)(15)
= 262½ units²
Total surface area of Triangle
= 262½ + 37½
= 300 units²
