Answer:
207 m²
Step-by-step explanation:
width = x
length = 3x - 4
2(length + width ) = Perimeter
2(3x - 4 + x) = 64
4x - 4 = 64/2
4x - 4 = 32
4x = 32 + 4
4x = 36
x = 9 m - width
length = 3x - 4 = 3 · 9 - 4 = 23 m
Area = length · width = 23 · 9 = 207 m²
Answer:
60
Step-by-step explanation:
Assuming that the triangle is a right triangle, we can reverse engineer the Pythagorean theorem (a^2+b^2=c^2).
60^2 + x^2 = 61^2
3600 + x^2 = 3721
x^2 = 3600 - 3721
x^2 = 121
x = sqrt121
x = 11
Answer: 5
Step-by-step explanation: The first piece of information that you need to know is that the product is the answer when two numbers are multiplied. Therefore, you need to multiply the two sets of numbers, and then subtract.
The formula will be:
(5 x 2) - (5 x 1)=
First, do what is inside the parentheses:
10 - 5=
And solve...
