The dimensions of the rectangular portion of the window should be 4 by 4.
To maximize area, we make the dimensions as close to congruent as possible. Since there will be 3 sides on the rectangular portion with a frame around them, we divide 12 by 3:
12/3 = 4
This means it should be 4 by 4.
Answer:
Simplifying
4x = 3x + 5
Reorder the terms:
4x = 5 + 3x
Solving
4x = 5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
4x + -3x = 5 + 3x + -3x
Combine like terms: 4x + -3x = 1x
1x = 5 + 3x + -3x
Combine like terms: 3x + -3x = 0
1x = 5 + 0
1x = 5
Divide each side by '1'.
x = 5
Simplifying
x = 5

Answer:
QR = 16 units
Step-by-step explanation:
Given that ΔPQR is right with hypotenuse QR
We can apply Pythagoras' theorem to find QR
QR² = 8² + (8)²
= 64 + 192
= 256
Take the square root of both sides
QR = = 16 units
Answer:
