In a 45 - 45 - 90 triangle the two smaller sides are =. So when you use
a^2 + b^2 = c^2, you need a and b both to find the area.
So call both of them = b^2.
Equation and solution
a^2 + b^2 = c^2
b^2 + b^2 = c^2
2b^2 = c^2
c = 24
b = ???
2 b^2 = 24^2
2 b^2 = 576 Divide by 2
b^2 = 288 I'm going to leave this as it is for the moment. You'll see what in a second.
Area of a triangle
Area of a triangle = 1/2 h * b
But the height and base are the 2 smaller equal sides of a 45_45_90 triangle
so h = b
base = b
Area of a triangle = 1/2 b^2 The equalities above tell you that. h and b of the triangle are equal.
Area = 1/2 288 feet^2
Area = 144 feet^2

Answer:
0.4 l of purple sand
Step-by-step explanation:
<u>Volume to be filled in:</u>
<u>Red sand</u>
<u>Blue sand</u>
- 35 centiliters = 35*10 ml = 350 ml
<u>Yellow sand</u>
- 2.5 deciliters = 2.5*100 ml = 250 ml
<u>Total volume filled:</u>
- 1000 + 350 + 250 = 1600 ml
<u>Purple sand needed:</u>
- 2000 - 1600 = 400 ml = 0.4 l
<u>Answer is</u> 0.4 l of purple sand required
