Question

The area of a rectangular plot is 340 sq. m. If its breadth is 17 m, find its length
and the perimeter.
​

Answer 1

Answer:

Length of the plot is 20 m

Perimeter of the plot is 74 m

Step-by-step explanation:

Formulae used:

  Area of rectangle = length × breadth

  Perimeter of rectangle = 2(l + b)

In the given question, let the length of the plot be 'x'.

Given,

Area of plot = 340 sq m

⇒ x × 17m = 340 m²

⇒ x = (340/17) m

⇒ x = 20 m

  ∴ Perimeter of plot = 2(l + b)

                     = 2(20 + 17) m

                     = 2(37) m

                     = 74 m

Answer 2

Given :-

The area of a rectangular plot is 340 sq. m. If its breadth is 17 m

To Find :-

Length

Perimeter

Solution :-

We know that

Area = Length × Breadth

340 = L × 17

340/17 = L

20 = L

Now,

P = 2(Length + Breadth)

P = 2(20 + 17)

P = 2(37)

P = 74 m
