How many sides has a square got? (4)
So if all the sides are 6cm.
Perimeter = 6 + 6 + 6 + 6
How many sides does an equilateral triangle have? (3)
All the sides are the same length in these shapes so again:
Perimeter = 6 + 6 + 6
Yes, an equilateral triangle has 3 congruent sides.
The area is: 15.6 (15.58846) square inches.
It does not have a circumference but its perimeter is: 4+6+8 = 18 cm
You have have know the length of all three sides - not just one side - and add them together.
A scalene triangle is a triangle that does not have a right angle in it (i.e. not a right angled triangle) and does not have two (or three) sides with the same length (i.e. not an isosceles triangle or an equilateral triangle). An example is a triangle with sides of length 4cm, 5cm and 6cm.
Probably an equilateral triangle
Yes, an equilateral triangle has 3 congruent sides.
16 cm
The area is: 15.6 (15.58846) square inches.
Area = 15.58846 cm2
For an equilateral triangle with side length a, area = (a²√3)/4, which for a= 6cm is 15.6 cm² [rounded to 1 decimal place]
22cm
Your square must have sides of 6cm so perimeter is 24cm.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
A square with a perimeter of 24 cm has an area of: 36 cm2
A right angle triangle fits the dimensions given
Perimeter is merely the total of the sides. A square has four sides so in this instance each side is 6cm.
