assuming its an isosceles triangle, then its 16 cm high
The area of a triangle equals 1/2 base x height. So the answer is 1/2 x 6cm x 8cm = 1/2 x 48cm2 = 24cm2.
I had this problem on my homework so, I can help. 1.Define the variable. A=area (48) B=base (12) H= height ? 2. Then write the literal equation, which is: 2a/b=h 3.Plug in variable: (2)48/12=h (2)48=96 96/12=8 h=8 3. Check: 12x8=96 4. Write a sentence. I hope this helped! : D
In general, answering a question which asks you to calculate the surface area of a shape means that you have to find the area of ALL the faces of that shape and add them up. In your case, you've got a rectangular prism (which in other words, is a cuboid.) Cubes and cuboids have 6 faces so you have to calculate the area of all 6 faces and then add them up.It is really very difficult to fully explain this in written words over the internet without any pictures or without being face-to-face explaining this to you since attempting a question like this requires a lot of visualising.I can however, just give you the answer.6 x 4 = 24cm26 x 4 = 24cm26 x 12 = 72cm26 x 12 = 72cm24 x 12 = 48cm24 x 12 = 48cm2 +----------------------= 288cm2Essentially what I did was calculate the area of each of the 6 faces based on the measurements you gave me and then added them up.NOTE: Remember, that what we are calculating is AREA and because the measurements were in centimetres, the units were cm2Hope that helps.Jamz159
Any number greater than or equal to 4*sqrt(48) = 27.71 cm (approx). Let the length, L, be any number greater than sqrt(48) = 6.93 cm (approx) and let W = 48/L cm. Then Area = L*W = L*48/L = 48 cm2 But since L can have an infinite number of values, so can the perimeter. For example, L = 48, W = 1, A = 48 and P = 98 L = 96, W = 0.5, A = 48 and P = 193 L = 480, W = 0.1, A = 48 and P = 960.2 L = 960, W = 0.05, A = 1 and P = 1920.1 L = 4800, W = .01, A = 48 and P = 9600.02 there is no limit to the size of P.
