Given

  • Length of rectangle = 24 cm
  • Breadth of rectangle = 16 cm
  • Perimeter of rectangle is equal to the perimeter of square.

To find

  • Side of the square.
  • Area of the square.

Explanation

  • In this question, we will solve the question in three parts.

⠀⠀⠀ Part 1

→ We will find the perimeter of rectangle by using the given values of length and breadth.

Part 2

→ Since, the perimeter of rectangle and square is same. Hence, we can easily find the measure of each side of the square.

⠀⠀⠀ Part 3

→ After finding the side, we can calculate the area of the square.

Solution

  • It is given in the question that length and breadth of the rectangle is 24cm and 16cm respectively.

\: \: \boxed{\tt{\bigstar{Perimeter_{(Rectangle)} = 2(l + b){\bigstar}}}}

\tt\longrightarrow{Perimeter = 2(24 + 16)}

\tt\longrightarrow{Perimeter = 2 \times 40}

\bf\longrightarrow{Perimeter = 80 cm}

  • Since, the perimeter of rectangle and square is equal.

\boxed{\sf{\orange{Perimeter_{(Rectangle)} = Perimeter_{(Square)}}}}

  • We have, perimeter of square is 80cm.

\: \: \: \: \: \: \boxed{\tt{\bigstar{Perimeter_{(Square)} = 4 \times side{\bigstar}}}}

\tt\longrightarrow{Perimeter = 80}

\tt\longrightarrow{4(side) = 80}

\bf\longrightarrow{side = 20}

Hence,

  • Each side of square is 20 cm.

  • Now, we will find area of the square.

\: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt{\bigstar{Area_{(Square)} = (Side)^2{\bigstar}}}}

\tt\longmapsto{Area = (20)^2}

\bf\longmapsto{Area = 400}

Hence,

  • Area of the square is 400 cm².

AnswEr :

  • Side of the square = 20cm
  • Area of the square = 400cm

Given :

  • The perimeter of a rectangle of sides 24cm and 16cm is equal to the perimeter of a square.

To Find :

  • Side and area of the square.

Solution :

Here

  • Length = 24cm ; Breadth = 16cm
  • Perimeter of the rectangle = Perimeter of the square.

As we know that

  • Perimeter of a rectangle = 2 (l + b)

Where

  • l = length
  • b = breadth

Now

→ Perimeter of the rectangle = 2 (l + b)

→ Perimeter of the rectangle = 2 (24 + 16)

→ Perimeter of the rectangle = 2 × 40

→ Perimeter of the rectangle = 80cm

°.° Perimeter of the rectangle = Perimeter of the square = 80cm

As we know that

  • Perimeter of the square = 4 × side

Now

Perimeter of the square = 4 × side

→ 80 = 4 × side

→ 80/4 = side

→ side = 20cm

As we know that

  • Area of a square = side²

According to question :

→ Area of the square = side²

→ Area of the square = (20)²

→ Area of the square = 20 × 20

→ Area of the square = 400cm²

Hence, the side and area of the square are 20cm and 400cm² respectively.
