You have to find the GCF of 140 and 180.
The GCF is 20 so thats your answer.
Given:
In the given ΔXYZ,
Base = 22
Height = 23.1
Also,
Base = 31.9
Height = 15.9
To find the area of the given ΔXYZ.
Formula
The area of a triangle is

where, b be the base and
h be the height.
Now,
Taking, b = 22 and h = 23.1 we get,
sq unit
Again,
Taking,
b = 31.9 and h = 15.9 we get,
sq unit
Therefore,
We can find the approximate area of the triangle by following two expression
a)
and
b) 
The top later is 5 because if the ladder is 10 inches half is 5 and the other half is 5
