Question

The area of triangle is' xy" wliere" x' is length and "y' is breadth. If thie length of rectangle is
increased by 5 units and breadth is decreased by 3 units, the new area of rectangle will be
a) (x+y)(x+3) (b) xy+15 (c) (x + 5)-3) (d) xy + 5-3​

Answer 1

Step-by-step explanation:

length=x

breadth=y

thereforearea=xy

newlength=x+5

newbreadth=y−3

nowarea=

(x+5)(y−3)=xy+5y−3x−15
