The area of square is : 400.0
Each side = 20/4 = 5 cm Area = 5*5 = 25 square cm
Area = 0.5*Base*Altitude = 0.5*20*5 = 50 square inches.
Area = 1/2*(12+20)*5 = 80 square feet
Area = 1/2*(12+20)*5 = 80 square feet
The base is 4 cm because 4*5 = 20.
50
Since the sides of a square with area of 25 are 5 each (5*5=25) the perimeter is going to be 4 * 5 = 20
A square with a side length of 5 feet (20/4) has an area of 25 square feet.
Lateral area of the prism excluding the two ends: (3*20)+(4*20)+(5*20) = 240 square units
Yes. Take the perimeter and divide by 4 to get the length of one side. Take that number and multiply it by itself and that's the area. ex. Perimeter = 20, then one side = 20/4= 5. Area = 5*5= 25.
squares have equal sides. Each side will be 5 meters because 20 divided by 4 = 5. Take length x width = area. 5x5=25. The area is 25 m2
