The third straw should be 29cm long in order to form right angles triangles

Application of pythagoras theorem

The theorem states that the square of the hypotenuse is equal to the square of the other two sides

Given the following

adjacent = 20 cm
Opposite side = height = 21cm

Required

Base of the ladder

Use the theorem

c^2 = 20^2 + 21^2

c^2 =  400 + 441
c^2 = 841
c = 29cm
