Answer:
143 inches
Step-by-step explanation:
Let the triangle be inches long.
Then the perimeter of the equilateral triangle will be inches.
Let the length of the square also be inches.
Then the perimeter is
It was given that the perimeter of the equilateral triangle is 77 inches more than the perimeter of the square.
So we can write the relation
Also, the side of the triangle is 55 inches longer than the side of the square.
So we write or
We put equation (2) into equation (1) to get;
We expand the bracket to get;
Hence the triangle is 143 inches long.

Answer:
14.01m
Step-by-step explanation:
Perimeter of the rectangular wire = circumference of the circle
Perimeter of the rectangular wire = 2(L+W)
Perimeter if the rectangular wire = 2(12+10)
Perimeter if the rectangular wire = 2(22)
Perimeter if the rectangular wire = 44m²
Circumference of the circle = πd
44 = πd
d = 44/3.14
d = 14.01m
Hence the circumference of the circle is 14.01m
