Step-by-step explanation:
1. Use the Pythagorean Theorem: a^2+b^2=c^2
You are already given c (the longest side) and one of the legs which could be a or b.
2. Plug the numbers into the formula and square them.
a^2 + 36^2 = 39^2
Squaring the numbers gives you: a^2 + 1,296 = 1,521
3. Subtract 1,296 from both sides and take the square root of the result.
a^2 = 225
= 15
Answer:
x (7+2x) = 372,
where 372 is the are of this rectangle, and is its width.
Step-by-step explanation:
The width of this rectangle is . Twice that width will be equal to
.
The length of this rectangle is seven more than twice the width of this rectangle, or seven more than . The length of this rectangle will thus equal to
.
The area of a rectangle is equal to the product of its width and its length. The width of this rectangle times its length will be equal to .
For this rectangle, this area is equal to 372. In other words,
.
This equation about represents the relationship between the width, length, and the area of this rectangle.
