What is the area of a triangle with base 2cm and height 3cm
You times the base and the height which is 2cm and 5cm which is 10 and because a triangle is halve of a square we divided by two which is 10 divided by 2 which is 5
Area: base × height
Area: 2×5
Area: 10
area of triangle = 10
An Area of a triangle with base 2cm and Height 5cm the answer has got to be 5
it depends what the shape is. for a square or rectangle it is simply length * width so if a rectangle has a length of 5cm and a width of 3cm then you do: 5*3=15 A=15cm^2 (A=area) (^2 means squared - area is expressed in centimetres squared, metres squared etc.) For a triangle you do 1/2 base*height. so if a triangle had a base length of 3cm and a height to the top of the triangle of 4cm then you would do: 3*4=12 12/2=6 A=6 /\ /\ : / \ : / \ : / \ \/ -------- Height <--------> base Finally circle is simply #r^2 (#=pi which is 3.1415 to 4.d.p but has an infinite number of non reccuring decimals) (r is the radius which is the distance between the centre of a circle and the edge) so if the radius of a circle was 2cm then you would first square that to get 4cm and then times it by pi which is about 12.566 there are formulas for pretty much every shape but they get more and more complicated the higher the number of sides.
Area= pi*r2If the diameter of the circle is 2cm, the A= pi cm2If the radius of the circle is 2cm, then: A=3.14159*4=12.567 cm2
A cube has all sides of length 2cm. What is the surface area and volume of the cube?
12cm is the answer
A scalene triangle is one type of triangle that will be formed from the given dimensions.
Area of a triangle = 0.5*base*height
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
5 cm2
Volume = base area x height so Base area = Volume / height. For example, if the volume is 10cm3 and the height is 2cm, 10/2=5, the base area must be 5cm2.
30
It is: 16 cm.
The lateral area of a cylinder with a diameter of 10cm and height of 2cm is approximately 62.83cm2
Any shape you want as long as the area within its boundary is 6cm2.examples:a triangle of base 6 cm and height 2 cm;a rectangle 2cm by 3 cm;an L shaped hexagon with sides 5cm, 2cm, 1cm, 1cm, 4cm, 1cm;circle of radius approx 1.382 cm;
height of triangle - 2cmbase of triangle - 10cmlength of prism - 10cmRemember, this is just one example I made up off the top of my head. There are plenty of others.
Base times height divided by two EXAMPLE :: Area = base times height divided by 2 = 5cm times 2cm divided by 2 = 10 divided by 2 = 5 cm
A = 1/2 BH A = 24 = 1/2 BH 24 * 2 = BH 48 = BH H = B - 2 48 = B(B - 2) B2 - 2B = 48 B2 - 2B - 48 = 0 (B - 8)(B + 6) = 0 B = 8 or -6 Since the base cannot be negative, the base is 8 and the height is 6 (8 - 2)
Base times height divided by two EXAMPLE :: Area = base times height divided by 2 = 5cm times 2cm divided by 2 = 10 divided by 2 = 5 cm
