Mrs.thomas bought a new blanket shaped like an equilateral triangle that measures 3 feet on each edge.how long should the ribbon be?
surely, 3+3+3 feet, no?
assuming the ribbon is to go once around the edges of the blanket...
To find out how long the ribbon should be, we need to determine the perimeter of the equilateral triangle blanket.
The perimeter of an equilateral triangle can be calculated by multiplying the length of one side by 3.
In this case, the length of one side is 3 feet.
So the perimeter would be:
Perimeter = 3 feet * 3 = 9 feet
Therefore, the ribbon should be 9 feet long.
To determine the length of the ribbon needed to go around the equilateral triangle-shaped blanket, we need to calculate the perimeter of the triangle.
In an equilateral triangle, all three sides are of equal length. In this case, each side measures 3 feet.
The formula to find the perimeter of an equilateral triangle is P = 3s, where P represents the perimeter and s represents the length of each side.
So, to find the perimeter of the triangle, we can plug in the given value:
P = 3 × 3 = 9 feet.
Therefore, the ribbon should be at least 9 feet long to go around the entire blanket.
