Answer 1

Question:

"A rectangle has 16 cm and 81 cm as dimensions . Find theperimeter of the square.Having the same area as of the rectangle."

Step-by-step explanation:

⤵️⤵️⤵️

Given:

• Length of the rectangle = 81cm
• Breadth of the rectangle = 16cm

Therefore, area of the rectangle = (81×16)cm² = 1296cm²

Now, it is given that area of the rectangle = area of the square

Therefore, 1296cm² = a², where a is the length of each side of the square.

=) √1296cm² = a

=) 36cm = a

Hence, perimeter of the square is equal to (4a)cm = (36 × 4)cm = 144cm (Answer)
