Question

the area of a rectangular lawn is the same as the area of an 18 long square if the length of the rectangular lawn is 27 find its perimeter.

pls answer step by step​

Answer 1

Solution

Given :-

• the area of a rectangular lawn is the same as the area
• Side of Square = 18 unit
• Length of rectangular lawn = 27 units

Find :-

• Perimeter of rectangular lawn

Explanation

Using Formula

★ Area of Square = (Side)²

★Area of Rectangle = (Length × Breadth)

★Perimeter of rectangle = 2 { (Length + Breathe)

So, According to question

==> Area of rectangular lawn = Area of Square

==> 27 × Breadth = (18)²

==> Breadth × 27 = 324

==> Breadth = 324/27

==> Breadth = 12

Now, Calculate perimeter of rectangular lawn

==> perimeter of rectangular lawn = 2 × ( 27 + 12)

==> perimeter of rectangular lawn = 2 × 39

==> perimeter of rectangular lawn = 78 units.

Hence

• perimeter of rectangular lawn will be = 78 units.
