Answer 1

I hope you understand..

Answer 2

$\huge\pink{Hey mate!!}$

◆Let breath be X ,then
◆Length =x+5
◆Area of rectangle=L×b
so, x×x+5
=xsquare +5

◆But area given that 618.75sq mtr

then, xsquare +5=618.75
this is very long solution so , just solve it and u will get the answer.

then you will get the area

◆Perimeter of rectangle
2(l+b) so, 2(x+x+5)
2(2x+5)
4x+10

◆perimeter 4x +10

hope this helps and pls mark as brainliest answer and follow me too..

any problem then ask me
