Question

The length of a rectangle is 7 cm less than twice it's breadth If the length is increased by two cm and the breadth is increased by 3 cm the perimeter of the resulting rectangle is 66 cm find the length and breadth of the original triangle

Answer 1

Answer:

Breadth = 13.3 cm

Length = 2(13.3 - 7) = 12.6 cm

Step-by-step explanation:

Breadth = x

Length = 2x - 7

Perimeter = 2(l+b)

If the length is increased by 2 cm and the breadth is increased by 3 cm, the perimeter will be 66 cm

2(x + 2x - 7) = 66

2(3x - 7) = 66

6x - 14 = 66

6x = 66 + 14

6x = 80

x = 80/6

x = 13.3 cm

Breadth = 13.3 cm

Length = 2(13.3 - 7) = 12.6 cm
