pythagroen theorem
for a right triangl of legs legnth a and b and hypotnuse c
a^2+b^2=c^2
legs are 3 and height
hypotnuse=legnth of lader=10

h^2+3^2=1^2
h^2+9=100
minus 9 both sides
h^2=91
sqr both sides
h=9.539
h=9.54 ft



4.
area=side^2 for a square
112=side^2
sqrt both sides
√112=side
(√16)(√7)=side
4√7 ft=side



3. 9.54 ft
4. 4√7ft

First question...

F = Floor = 3

W = Wall = ?

H = Hypotenuse = 10

-----

3² + W² = 10²

W² = 10² - 3²

W² = 91

W = √91

Answer (3) : √(91) feet [Rounded: 9.54 feet]

---------

Last question...

L² = 112

L = √(112) = √(28)√(4) = √(7)√(4)√(4) = 4√(7)

Answer (4):

4√7 feet
