Question

7. The length of a rectangle is 2 more than 3 times its breadth. If both length and breadth are increased
3 units, the new perimeter becomes 2 times the original. Find the length and breadth of the length and breadth of the rectangle​

Answer 1

Answer:

Let te breadth of the rectangle be x.

→ length = 3x + 2

According to the condition in the question, we get

2[(x + 3) + (3x + 5)] = 2{2[x + (3x +2)]}

→ 2(4x + 8) = 4(4x + 2)

→ 8x + 16 = 16x + 8

→ 8x = 8

→ x = 1

→breadth = 1

length = 3x + 2 = 3(1) + 2 = 5
