Hi everyone, so in this question a chart is given between perimeter p and side of square s, okay? and it is also given side 1 is equal to 3 cm and side 2 is equal to 5 cm.
00:17
So in first sub -quotion we have to find delta s and delta is nothing but s2 minus s 1, that different between sides, okay? so 5 minus 3 is equal to 2 cm.
00:33
In second sub -position, we have to find what is the increase of the area.
00:40
Like when the side is 3 cm and so what is the area and when side is the 5 cm, what is the area? so as we know, sorry, not area, perimeter, so as we know, p is equal to 4 into s.
00:58
Like 4 into side.
01:03
So for p3, like when s or side equals to 3, so 4 into 3 is equal to 12 and when p 5, 4 into 5 is equal to 2...
