# <span lang="EN-GB

Answer :

Perimeter of the given rectangle = 240 cm

Let the length of the rectangle = x cm

Let the breadth of the rectangle = y cm

According to the question

2(x + y) = 240

x + y = 240(i)

(divide by 2 on both the sides)

Let the new length be   Let the new breath be   According to the question  (divide by 2 on both the sides)

From    (take L.C.M on both side and solve)

x = 2y

(multiply by 10 on both the sides and solve)

x-2y = 0(iii)

subtracting (iii)from (i)

x-2y-x-y = -120

-3y = -120

y = 40

Put the value of y in (i)

x + y = 120

x = 120-40

x = 80

The breath = 40 cm

The length = 80 cm

Hence, length of the 2nd rectangle Breath of the 2nd rectangle Rate this question :
