6 cm because well you tell the rest***************************************An equilateral triangle has three sides of equal length.Therefore: if the length of one side measures 18cm then 18 x 3 = 54 centimetre is the perimeter.
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
18cm
The given dimensions would not form a right angle triangle but in general the are of a triangle is 0.5*base*perpendicular height
Since an isosceles triangle can be represented by two right triangles back to back, you can utilize the pythagorean theorum to solve this example. Specifically: 18cm/2 = 9cm = 1 leg of right triangle (A) 24cm = hypotenuse of right triangle (C) A squared + B squared = C squared Altitude = B = square root of (C squared - A squared) = approximately 19.875
