If similarity ratio means the ratio between the lengths of the cubes:
For this case we have the following system of equations:
We must solve the system by the method of elimination. To do this we multiply the second equation by -3, then:
We add both equations:
We find the value of "x":
Thus, the solution of the system is:
We verify:
Is fulfilled!

Answer:
11 feet = 132 inches
The boards are x, x and (x-3) inches long.
x + x + x -3 = 132
3x = 135
x = 45
The boards are 45 inches, 45 inches and 42 inches long.
A) 22 x 1 = 22m²
b) 22 x 4 = 88m²
c) 22 x 9 = 198m²
d) 22 x 16 = 352m²
e) 22 x 251 = 5522m²
f) 22 x 4 = 88m²
g) 22 x 9 = 198m²
h) 22 x 16 = 352m²
i) 22 x 25 = 550m²
j) 22 x 3636 = 79992m²
Answer:
Given that △ABC is an isosceles right triangle.
<em><u>Since the base BC=30 cm, therefore, AB=30 cm.</u></em>
Area of △ABC:
A=21×AB×BC=21×30×30=450 cm2
<h2>
<em><u>Hence, area of △ABC is 450 cm2.</u></em></h2>
