Question

one side of a rectangle is increased by 5 cm and other is decreased by 3 cm and the square is formed whose area is 256 CM square then perimeter of the rectangle is​

Answer 1

Step-by-step explanation:

Let length =l       length =ω⇒

(1)l−4=ω+3...(1)

⇒l=ω+8

(2)l.ω=(l−4)(ω+3)

(ω+8)(ω)=(ω+3)2

ω2+8ω=ω2+9+6ω

ω=9⇒l=17

∴ Perimeter =2(l+ω)

=2(9+17)=2×26

=52m
