The widths of the bars are equal to ensure that numbers aren't represented improperly. If a bar was wider than another that was the same height, it could be misinterpreted as being larger. 
        
             
        
        
        
Answer:
(a is size of side of triangle)
the perimeter of equilateral triangle =3a
or, 36=3a
Thus, a = 13cm
area of equilateral triangle
=√3/4*(a^2 )
=√3/4*(13^2)
=73cm^2

We have been given the measure of two parallel sides as 11 m and 5 m. And we are given one of the slanted sides as 4 m.
From the given information, we can find the base of one of the side triangles as 3 m.
Therefore, upon using Pythagorean theorem, we get the set up for height as


Therefore, height of the required figure is  m
 m
 
        
             
        
        
        
Let x and y be the 2 integers.
Then  x = 4y - 2
and xy = 90
Substitute for x in the second equation:-
(4y - 2)y = 90
4y^2 - 2y - 90 = 0
2y^2 - y - 45 = 0
(2y + 9)(y - 5) = 0
so y = 5     ( as it is an integer)
and x =  = 90/5 = 18
Answer:-  The 2 integers are 5 and 18.
