Perimeter = 3*25 = 75 cm
3 times 14cm = a perimeter of 42cm
3*3 = 9 cm
7 cm x 3 sides = 7 x 3 = 21 cm perimeter.
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
7 cm x 3 sides = 21 cm perimeter.
7 cm x 3 sides = 21 cm perimeter.
If a triangle with a perimeter of 24 cm is an equilateral triangle, then each of its 3 sides will be 8 cm in length
Perimeter = 3*25 = 75 cm
8cm !
3 times 14cm = a perimeter of 42cm
3*3 = 9 cm
9+9+9 = 27 cm
7 cm x 3 sides = 7 x 3 = 21 cm perimeter.
22.5 cm
Perimeter of Triangle = a + b + cso if you have an equilateral with say 4 cm sides you would add4+4+4=12cmJust add up its 3 equal sides
