Dear Student,

◆ Answer

Width of the rectangle = 70 cm

● Explanation -

Let l and b be length and breadth of the rectangle.

Given that -

l = 2.5 b

Perimeter of rectangle is given by -

Perimeter = 2 (l + b)

490 = 2 (2.5b + b)

490 = 2 × 3.5b

b = 490/7

b = 70 cm

Hence, width of the rectangle is 70 cm.
