19,765 but couldnt u just use a calculator??
Step-by-step explanation:
given, b=2
now,
=b.5
=2.5
=10
3 radical 70. 9 times 70 is 630, 9 squared is 3.
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
The answer is 1:2. all you have to do is add the dots for example 4/5 would be 4:5
