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 triangle is calculated using the formula: Area = 0.5 * base * height. In this case, the base is 18cm and the height is 12cm. Plugging these values into the formula, we get Area = 0.5 * 18cm * 12cm = 108 square centimeters. Therefore, the area of the triangle is 108 square centimeters.
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
perimeter is the total distance around the outside of the 2D shape. So if we had a triangle for example: 1st side = 5cm 2nd side = 7cm 3rd side = 6cm 5 + 7 + 6 = 18cm That is your answer.
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
18cm 2
To calculate the area of a triangle, you use the formula: Area = 0.5 x base x height. Plugging in the values given, the area of the triangle would be 0.5 x 18cm x 20cm = 180 square centimeters.

It is: 162/9 = 18cm
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
1/2b*h 180 cm^2
12 + 24 + 18 = 54cm (Or 0.54 metres)
Perimeter = 2 x L + W so L + W = 9, this would be 6 x 3 to give area of 18
