Answer:
Explanation:
Let's call the length of the shorter leg of the isosceles trapezoid "a" and the length of the longer leg "b".
From the problem, we know that:
a = 0.1x - 0.5 (length of one leg is 0.1.x - 0.5 meters)
b = 0.3x - 2.1 (length of the other leg is 0.3.x-2.1 meters)
Since we know that the trapezoid is isosceles, we know that a = b. So we can set the two expressions equal to each other:
0.1x - 0.5 = 0.3x - 2.1
Now we can solve for x:
0.2x = 1.6
x = 8
Now that we know x, we can substitute it back into the expressions for a and b to find their lengths:
a = 0.1(8) - 0.5 = 0.3 meters
b = 0.3(8) - 2.1 = 0.3 meters
Therefore, each of the legs of the solar panel are 0.3 meters long.
