Answer:
Step-by-step explanation:
Let the number be .
Then,
This implies that;
We multiply both sides by to obtain;
Or
Answer: 11
Step-by-step explanation:
Since the smaller triangle is half of the larger triangle
5.5×2=11
Area = length *width
A = x²
3x² = (x+10)(x+12)
3x² = x²+10x+12x+120
3x² = x²+22x+120
3x²-3x² = x²+22x+120-3x²
0 = -2x²+22x+120
Factor to solve for x:
-2(x²-11x-60)
(x+4)(x-15)
x = -4 & x = 15 but we can't have a negative length so we eliminate 4. The length of the square is 15 cm.
