Answer:
We know Perimeter of a rectangle= 2(l+b)
Taking Length as x+5
Breadth as x
the length is 5 more than breadth, therefore the equation can be
2(l+b)=90
2(x+{x+5})=90
2(2x+5)=90
4x+10=90
4x=90-10=80
x=80/4=20
therefore the breadth=x=20m
Length=x+5=20+5=25m
Also find area
that is area of a rectangle= l×b
it is
20×25=500m²
therefore the rectangle=
Length=25m
Breadth=20m
Perimeter=90m
Area =500m²
