If you mean an area measuring 3m x 8m, the answer is 22m !
Assuming this is a rectangular prism, the surface area would be 2LW+2LH+2HW. So the surface area for this object would be: 2*3*5+2*3*8+2*8*5=30+48+80=158 square meters.
32m. Area_of_square = side2 -> side = √area -> side = √64m2 = 8m Perimeter_of_square = 4 x side -> Perimeter = 4 x 8m = 32m
This is not the question I was looking for.1Record the length and width of a square or rectangle. Substitute your measurements into the formula "length x width" to solve for area. For example, a rectangle with a length of 7 meters (m) and a width of 3m has an area of: 7m x 3m = 21m^2 (21 meters squared, or 21 square meters).2Use the formula "(base x height)/2" to find the area of a triangle. A triangle with a height of 7m and a base of 3m has an area of 7m x 3m = 21m^2, divided by two equals 10.5m^2.
6 Meter x 3 Meter = 18 m2
