Question

the length of rectangle is thrice its breadth and its perimeter is 48 cm. find the length and breadth of the rectangle​

Answer 1

Answer:

Given : the length of rectangle is thrice its breadth and its perimeter is 48 cm.

____________________

Step-by-step explanation:

Let the Breadth of the rectangle be x cm.

Therefore, Length will be 3x cm.

★ According to question now,

❅ Perimeter = 2 (Length + Breadth) ❅

➳ 2 (l + b) = 48

➳ 2 (3x + x) = 48

➳ 6x + 2x = 48

➳ 8x = 48

➳ x = 48/8

➳ x = 6

Therefore,

Breadth of the rectangle = x = 6 cm

Length of the rectangle = 3x = 3(6) = 18 cm
