Question

Q 1 a) If the length of a rectangle is twice its breadth. Compute its area, if its breadth is taken as x cm

b) If now, the length is four times the breadth. Compute the new Area.

c) Compare, by finding the ratio of the original area to the new Area.

d) What do you observe in comparing the two Areas

Answer 1

Step-by-step explanation:

(a) Let the breadth=Xcm

length=2x cm

area of Rectangle= L×b

x×2x=2x²

(b)Breadth=Xcm

length= 4x cm

area= x×4x= 4x²

(c) ratio of both rectangles= 2x²/4x²=1/2= 1:2

(D) we can observe that the area of new rectangle is double of area of original rectangle
