How do you find the area of the right angle triangle given the base hypotenuse and perimeter?
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
What is the surface area of a right prism?
The surface area of a right prism is the sum of the areas of all its faces. The formula for calculating the surface area of a right prism is 2 × (base area) + (lateral area), where the base area is the area of the base shape and the lateral area is the sum of the areas of the remaining faces. The lateral area can also be calculated by multiplying the perimeter of the base shape by the height of the prism.
Which formula can be used to find the surface area of a rectangular prism?
surface area=(perimeter of base)x(height of the shape)+(area of the base)x(2)
What is the surface area of a prism with a base perimeter of 20 height of 2 and area of the base 50?
Since the perimeter of the base is 20 and the height of the shape is 2, we can find the area of the sides by multiplying these together. 20 x 2 = 40 The area of the top and base are given as 50 square units each, so we add 2 lots of 50. 40 + 50 + 50 = 140 square units.
How do you find the perimeter of a rectangle when only the base and area are given?
If the shape is a rectangle...We know that the AREA equals BASE x WIDTH ... A equals B*WIf we divide both sides by B we get: W equals A/BWe know that the PERIMETER equals ( 2 x BASE ) + ( 2 x WIDTH ) ... P equals 2B+2WWe can substitute W in the perimeter formula as follows:P equals 2B+2WP equals 2B+(2*A/B)So... if you know the Base and Area, you should now use this new formula to get the Perimeter.

How do you determine perimeter if given the area?
To find area given perimeter, rename perimeter to circumference and solve with these formulas: Circumference = 2πr (or 2 * π * r) Area = πr^2 (or π * r * r) With these the area can be found from circumference(or perimeter) as follows: A = π(C / 2π)^2 Now, to find the perimeter given the area; We use A = πr^2 and rearrange then solve: r = √(A / π) So, the circumference would be 2πr = 2π√(A / π)
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base

Find base if height and area are given?
Of a square? (area/height=base) Of a triangle? ({area/height}/2=base) Or of some other shape?
How do you work the height out with the area and the base is given?
If the shape in question is a triangle, then Area = 0.5 * Base * Height So Height = 2 * Area / Base
How do you find the length of the base when the area is given?
It depends upon the shape. For example, if it is a parallelogram, then divide the area by the height to get the base.
How do you find the area and the perimeter?
For the perimeter add up all the lengths of the sides. The area is a bit more complicated as it depends upon the shape. However, by dividing any shape up into smaller shapes, the area for which can be found (eg rectangles: area = length × width; triangles: area = ½ × base × height), the area of the original shape can be calculated as the sum of these areas.
What can you say about the shape area and perimeter of two parallelogram that have the same base and height?
That they could be congruent if they have the same interior angles
