Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
12cm (4 sides x 3 = 12)
A scalene triangle
Perimeter of rectangle: 5+3+5+3 = 16cm
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
Well, honey, making a shape with a perimeter of 9cm is as easy as pie. You could have a triangle with sides measuring 3cm, 3cm, and 3cm. Or you could have a rectangle with sides measuring 2cm and 2.5cm. Just remember, the perimeter is the sum of all the sides, so get those measuring tapes out and get creative!
Height of an equilateral triangle = √3 / 2 x side = (√3 / 2 ) x 3 = 2.598 cm.
it is a equilateral triangle and 3cm each side base times high divided by 2 so........... 3x3=9 divided by 2= 4.5 cm
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
An isosceles triangle
It is probably an isosceles triangle.Isosceles triangle = 2 sides the same lengthUnless the 3rd side is also 3cm, in which case it would be an equilateral triangle.
The triangle with side lengths of 3cm, 5cm, and 3cm is classified as a scalene triangle. A scalene triangle is a triangle in which all three sides have different lengths. In this case, the three sides have lengths of 3cm, 5cm, and 3cm, making it impossible for the triangle to have any congruent sides or angles.
To draw a shape with a 9cm perimeter, you can create a triangle, square, or rectangle. For a triangle, you could have sides measuring 3cm, 3cm, and 3cm. For a square, all four sides would be 2.25cm. For a rectangle, two sides could be 2cm and the other two sides could be 2.5cm. These shapes will all have a perimeter of 9cm.
With 3cm for each sides.
