Answer:
5.4 m
Step-by-step explanation:
The Pythagorean theorem tells you the relationship between the various lengths is ...
cd² = ac² +ad²
cd² = (2.4 m)² + (1.8 m)² = 9.00 m²
cd = √(9.00 m²) = 3.0 m
Since cd = cb and ab = ac+cb, we have ...
ab = 2.4 m + 3.0 m = 5.4 m
_____
You may recognize this as a 3-4-5 right triangle with a scale factor of 0.6. We are asked for the sum of the lengths of the "4" and "5" legs, which is ...
0.6·(4+5) = 5.4
Answer:
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the ratio of the sides of the rectangular window is:
Then, let be 
the width (in inches) of the rectangular window and 
the lenght (in inches) of the rectangular window.
Knowing that the area of the window is 2,720 square inches, you can know that:
Now you must solve for "x" in order to find the width:
Finally, the lenght is:
