Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
12cm (4 sides x 3 = 12)
A scalene triangle
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
Perimeter of rectangle: 5+3+5+3 = 16cm
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.
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.
An isosceles triangle
20cm
With 3cm for each sides.
