Answer: 1: 34 units    2: 24.5

Step-by-step explanation:

For figure 1, just split the area into squares and triangles and find the area of each. If you split figure 1 into 1 square and 3 triangles you get...

4x4= 16

(4x3)/2= 6

(4x4)/2= 8

(4x2)/2= 3

16+6+8+3 = 34

You do the same for figure 2, but use 4 triangles and 1 tiny square

1x1= 1

(4x3)/2= 6

(3x3)/2= 4.5

(4x4)/2= 8

(5x5)/2= 5

1+6+4.5+8+5= 24.5

You shouldn't need to worry about negative numbers because you are looking at the area

you are told that the sun pf another two whole numbers is 20 ans thair differnece is 15 is this possible
-Dominant- [34]

This is not possible if both numbers are whole numbers.

The larger number would be

(20+15)/2 = 17.5

The smaller number would be

(20-15)/2=2.5

So they cannot be whole numbers.
