find Area of surface of 12 meters, 5 meters, and 4 meters
the area will be three pairs of rectangles, of dimensions 12x5, 12x4, 5x4.
I assume you know how to find the area of a rectangle...
As = (L*W)*2 + (L*h)*2 + (W*h)*2
As = (12*5)*2 + (12*4)*2 + (5*4)*2 = __m^2.
To find the area of a surface, we need to know the shape of the surface.
If the surface is a rectangle, the formula for finding the area is:
Area = length × width
Given that the measurements are 12 meters, 5 meters, and 4 meters, it is not clear how these measurements relate to the dimensions of a rectangle.
If you meant to provide measurements for three different sides of a rectangular prism (a three-dimensional object), then the area of one of the surfaces can be calculated using the formula:
Area = length × width
For example, if the measurements represent the length, width, and height of a rectangular prism, then the area of one of the surfaces would be:
Area = 12 meters × 5 meters = 60 square meters
However, if you meant to find the surface area of the entire rectangular prism, we need all three dimensions.
The formula for finding the surface area of a rectangular prism is:
Surface Area = 2(lw + lh + wh)
Where "l" represents the length, "w" represents the width, and "h" represents the height. With the given measurements, we can calculate the surface area by substituting the values into the formula.
