Answer:

29 feet for second ladder

Step-by-step explanation: I dont think first is possibe(decimals), second 21 square+ 20 square= 441+200=881, root of 881 is 29.

Answer:

As this is a right angled triangle, simply find the hypotenuse

Step-by-step explanation:

We know that the square of hypotenuse is equal to the sum of the square of the other two sides

In formula > h²=a²+b²

We know the values of a and b.

Now simply put the values into the equation to find the answer :)

For 1,  h²= 25² + 10²

h² = 625 + 100

=725

h=√(725)

=26.92 feet

Therefore height of ladder = 26.92 feet

For 2,

h²= 21²+20²

h²=441 + 400

h² = 841

h = √841

h = 29 feet

Heigh of ladder = 29 feet
