Answer 1

Step-by-step explanation:

=>Perimeter of square=side+side+side+side

= side×4

= 6×4

= 24cm

=>The perimeter of the square is 24cm

Answer 2

Step-by-step explanation:

Let the base of the triangle then altitude of the triangle

Hypotenuse = 13 cm

By Pythagoras theorem

(Hypotenuse) 2 = (Base)2 + (altitude)2

begin mathsize 12px style open parentheses straight x minus 12 close parentheses open parentheses straight x plus 5 close parentheses equals 0

straight x equals 12 space space space or space space space space straight x equals negative 5 end style

Length can not be negative hence we choose x = 12 cm

Altitude = x - 7 = 12 - 7 = 5 cm
