Let
the length and
the width. By the ratio of the sides:
Now, we'll find the perimeter p. We'll use the formula below:
The area of a rectangle is
. Then:
Answer:
12
Step-by-step explanation:
You would substitute
4(4)-4
then simplify
16-4
then subtract
12
Answer:
Yes!
Step-by-step explanation:
Lets say you have 4 numbers. (1-4)
Draw a box and separate the box into 4's (1 for each number)
On 2 sides of the whole box write the numbers (1 on one side, 2 on the same side but below it, 3 on the top of the box, 4 besides the other number)
After setting it up, you multiply them just like a times table.
In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.
