P=52 yards
p=26 yards
A=square p(p-a)(p-b)(p-c)
A=square26(26-12)(26-16)(26-24)
A=square 26x14x10x2
A=85 yards^2
Answer:
or 2.738
Step-by-step explanation:
Let’s just look at the triangle on the top with the on the top and x on the bottom. (Basically the top half to the equilateral triangle)
There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem:
We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b= or
Plugging these values into the equation:
x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}
This approximately equals 2.738
Formula for perimeter of triangle: P=2width+2length
width=x
length=y
446=2x+2y
y+5=3x | subtract 5
y=3x-5
446=2x+2(3x-5)
446=2x+6x-10
446=8x-10 | add 10
456=8x | divide\ by\ 8
x=57
y=3x-5=3*57-5=166
Length=166 yards
width=57 yards
