Question

the area of rectangle is 102sq. CM if the length is 17 what is the perimeter​

Answer 1

46 m

Step-by-step explanation:

Given:

We are given that, area and length of the rectangle is 102 cm² and 17 cm respectively.

To find:

We need to find the perrimeter of rectangle.

Solution:

To find the perimeter of rectangle, firstly we should know the value of breadth. By applying area of rectangle formula, we can find the breadth of the rectangle.

⇒ Area = Length × Breadth

⇒ Breadth = Area/Length

⇒ Breadth = 102/17

⇒ Breadth = 6 cm

Hence, breadth of the rectangle is 6 cm. Now, on using perimeter of rectangle formula, we get:

⇒ Perimeter = 2 × (Length + Breadth)

⇒ Perimeter = 2 × (17 + 6)

⇒ Perimeter = 2 × 23

⇒ Perimeter = 46 m

Hence, the perimeter of the rectangle is 46 m.
