Question

The area of rectangular plot is 2400 square meters and it's length is 15 times to it's bread
What is the perimeter?​

Answer 1

Given :-

• The area of rectangular plot is 2400 square meters and it's length is 15 times to it's breadth

To find :-

• Perimeter of rectangle

Solution :-

• Area of rectangular plot = 2400 m²

Let the breadth be x then its length is 15x

As we know that

Area of rectangle = l × b

Where " l " is length and " b " is breadth of rectangle.

According to question

→ Area of rectangular plot = 2400

→ l × b = 2400

→ 15x*x = 2400

→ 15x² = 2400

→ x² = 2400/15

→ x² = 160

→ x = √160 = 12.6 m

Hence,

• Length of rectangle = 15x = 189m
• Breadth of rectangle = x = 12.6m

Perimeter of rectangular plot

→ 2(l + b)

→ 2(189 + 12.6)

→ 2 × 201.6

→ 403.2 m

Therefore,

• Perimeter of rectangular plot is 403.2m
