1.	The ratio between the length and the breadth of a rectangle is 17 : 13. If breadth is 5 cm less than the length, what will be the perimeter of the rectangle? 1. 115 cm2. 95 cm3.125 cm4. 75 cm
Answer» Correct Answer - Option 4 : 75 cm Given: Ratio between the length and the breadth of a rectangle = 17 : 13 Breadth is 5 cm less than the length Formula used: Perimeter = 2(Length + Breadth) Calculation: Let the length and breadth of rectangular lawn be 17a and 13a According to the question ⇒ 17a – 13a = 5 ⇒ 4a = 5 ⇒ a = 5/4 cm Length = 17 × 5/4 = 21.25 Breadth = 13 × 5/4 = 16.25 Perimeter = 2(21.25 + 16.25) = 75 cm ∴ The perimeter of the rectangle is 75 cm

Answer» Correct Answer - Option 4 : 75 cm

Given:

Ratio between the length and the breadth of a rectangle = 17 : 13

Breadth is 5 cm less than the length

Formula used:

Perimeter = 2(Length + Breadth)

Calculation:

Let the length and breadth of rectangular lawn be 17a and 13a

According to the question

⇒ 17a – 13a = 5

⇒ 4a = 5

⇒ a = 5/4 cm

Length = 17 × 5/4 = 21.25

Breadth = 13 × 5/4 = 16.25

Perimeter = 2(21.25 + 16.25) = 75 cm

∴ The perimeter of the rectangle is 75 cm
