Let us denote the smaller even integer by N.
Then, the next even integer must be N+2.

To verify, set N as any even number, say 174.
Then, the next even integer must be 2 more than this number, i.e. 174+2=176.

The sum of these two consecutive even integers can be expressed as:
                                    N+(N+2)=2N+2

We are told that this sum divided by four is 189.5, i.e.
                                     (2N+2)\div4=189.5

Multiplying both sides by 4 will reverse the division:
     (2N+2)\div4\times4=189.5\times4
     (2N+2)\times1=758

Subtracting 2 from each side will reverse the addition:
     2N+2-2=758-2
     2N=756

Dividing both sides by 2 will reverse the multiplication:
     2N\div2=756\div2
     N=378

Therefore, the two consecutive integers must be 378 and 380.

Check this:
     (378+380)\div4=758\div4=189.5

Explain please and tell me how to do it ?

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.

Total area = area of square + area of rectangle + area of triangle

= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)

= (9 + 32 + 7.5) cm^2

= 48.5 cm^2 (total area of figure)
