How do you find the area of a figure if the base is a variable?

There are two possible ways:
The first is to obtain a formula for the area which depends on a variable (the base). For example, consider all triangles with a base of x cm and a height of 4 cm. What is their area?
Answer: it is 1/2*height*base = 1/2*4*x = 2x cm2. So I have an answer which includes the variable representing the base.
The second possibility is that there is supplementary information that allows you (if you work hard enough) to find a value for the base.

What is always true about the area of a rectangle?
You can always find the area of a triangle - by dividing the length of the base by 2, then multiplying that figure by the height.
How do find the area of an isosceles tringle?
The area of ANY triangle is base x height. The height must be measured perpendicular to the base. In the case of an isosceles triangle, if you know only the length of the sides, you can figure out the height by Pythagoras' Theorem.
How would you find the area of the remaining figure?
To find the area of the remaining figure, subtract the area of the removed portion from the total area of the original figure.
How can you find the surface area of a box including the bottom and the top?
Lateral Area= p times h p= perimeter of the base h=height of the figure Surface Area= Lateral Area + 2 times (B) B= Area of base
What is a formula for surface area of triangle?
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
Find the area of 6 base and 10 height?
If the figure is a rectangle, the area is 60. If the figure is a triangle, the area is 30.
How do you figure out the surface area of a triangular prism?
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
How do you find an area from perimeter?
Depends on what figure you are working on, each figure has its own formula for the area. So you need to do a sketch and label the relevant quantities which are needed to find the area. By using the perimeter value, find a formula for one quantity in terms of the other(s). Write the area as a function of just one variable. Find the domain of that variable. After that, use the derivative to find the desired global maximum or minimum (the highest or lowest points on the curve), which will give you the maximum or the minimum area of the figure you are interested in. If you have a specific problem, I can help more.
How do you find the lateral area of a rectangular prism?
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
What is always true about the area of a rectangle?
You can always find the area of a triangle - by dividing the length of the base by 2, then multiplying that figure by the height.
What is the area of a triangle with a base of 12 inches and a height of 8 inches?
48in2. To find the area of any triangle - you divide the length of the base by 2, then multiply that figure by the height.
How do find the area of an isosceles tringle?
The area of ANY triangle is base x height. The height must be measured perpendicular to the base. In the case of an isosceles triangle, if you know only the length of the sides, you can figure out the height by Pythagoras' Theorem.
How do find the area of a plane figure?
Area of plane figure
How would you find the area of the remaining figure?
To find the area of the remaining figure, subtract the area of the removed portion from the total area of the original figure.
How can you find the surface area of a box including the bottom and the top?
Lateral Area= p times h p= perimeter of the base h=height of the figure Surface Area= Lateral Area + 2 times (B) B= Area of base
How do you find the volume of a figure made of cubes and prisms?
The volume V of a prism is the area of its base Btimes its height h.
To find the surface area of a three dimensional figure what do you have to find?
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
