It is: 4*5 = 20cm
20cm/4sides = 5cm 5cm*5cm = 25cm^2
25 cm
If you know only the base and height, you have two unknown sides and it is not possible to calculate the perimeter. The perimeter can have any value greater than or equal to 5+sqrt(89) cm.
you only need to measure 1. say it was a square with a side that's 5cm long then you go 5x4 and you've got the answer: 20cm perimiter!
5cm because the square root of 121 is 11 and 5 plus 6 equals 11.
Perimeter = sum of all side lengths. For a square, s1 = s2 ... = s4, so Perimeter = 5+5+5+5 = 4(5) = 20cm
20
20cm/4sides = 5cm 5cm*5cm = 25cm^2
4 x 5cm = 20cm
5cm
A square has all four sides the same length, so perimeter = 4 x side length.4 x 5cm = 20cm.
200mm
No, the length of one side can't be greater than the perimeter.
20 cm
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
25 cm
If you know only the base and height, you have two unknown sides and it is not possible to calculate the perimeter. The perimeter can have any value greater than or equal to 5+sqrt(89) cm.
