Answer 1

Answer:

Refer the below for the actual concept and refer the attachment for your answers

Step-by-step explanation:

original width =x cm

and length =y cm

new width =x-15 cm

and length =y-25 cm

therefore

area of the rectangle = L*B

= (x-15)(y-25)

=xy-25x-15y+375

PERIMETER =2(L+B)

= 2 (x-15+y-25)

= 2 (x+y-40)

=2x+2y-80
