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
