Answer:
The side of first square =14 units
side of second square =4 units
Step-by-step explanation:
We have given two squares,
A square have all its four sides equal and at right angles.
Let the side of first square be 'a'
and the side of second square be 'b'
Given:
[tex]a-b=10[/tex] equation:1
[tex]a+b=18[/tex] equation:2
Solving equation:1
a=10+b equation:3
Putting 'a' in equation:2
[tex](10+b)+b=18\\\\2b=18-10\\\\2b=8\\\\b=4[/tex]
Putting 'b' in equation:3
[tex]a=10+4\\\\a=14[/tex]
So, the side of first square is 14 units and
side of second square is 4 units
