<h3><u>Answer </u><u>1</u><u> </u><u>:</u><u>-</u></h3>
<u>We </u><u>have</u><u>, </u>
- <u>The </u><u>area </u><u>of </u><u>rectangular </u><u>floor </u><u>is </u><u>3</u><u>2</u><u> </u><u>m²</u>
- <u>Breath </u><u>is </u><u>half </u><u>of </u><u>its </u><u>length </u>
<h3><u>Therefore</u><u>, </u></h3>
Let the length of the rectangular field be x
<u>So, </u>
Breath of the rectangular field will be x/2
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Thus, The length of rectanglular field is 8m
<u>Therefore</u><u>, </u>
Breath of the rectangular field will be
<h3><u>Now</u><u>, </u></h3>
<u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>perimeter </u><u>of </u><u>the </u><u>given </u><u>rectangular </u><u>field </u>
<u>We </u><u>know </u><u>that</u><u>, </u>
Perimeter of the reactangle
<u>Subsitute </u><u>the </u><u>required </u><u>values </u><u>in </u><u>the </u><u>above </u><u>formula </u><u>:</u><u>-</u>
Perimeter of the rectangular field
Hence, The perimeter of the rectangular field is 24 m
<h3>
<u>Answer </u><u>2</u><u> </u><u>:</u><u>-</u></h3>
<u>We </u><u>have </u>
- <u>The </u><u>perimeter </u><u>of </u><u>square </u><u>is </u><u>1</u><u>2</u><u> </u><u>cm</u>
Let the side of the square be x
<u>We</u><u> </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values </u><u>in </u><u>the </u><u>above </u><u>formula </u><u>:</u><u>-</u>
Thus, The length of the square is 3 cm
<h3>
<u>Now</u><u>, </u></h3>
<u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>area </u><u>of </u><u>square </u>
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Area of square
Hence , The length and area of square is 3cm and 9 cm²
<h3>
<u>Answer </u><u>3</u><u> </u><u>:</u><u>-</u></h3>
<u>We </u><u>have </u>
- <u>The </u><u>perimeter</u><u> </u><u>of </u><u>square </u><u>feild </u><u>is </u><u>6</u><u>0</u><u> </u><u>m</u>
Let the side of the square feild be x
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Thus, The side of the square feild is 15m
<h3>
<u>Now</u><u>, </u></h3>
<u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>area </u><u>of </u><u>square </u>
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Area of square
Hence, The area of square feild is 225 cm²
<h3>
<u>Answer </u><u>4</u><u> </u><u>:</u><u>-</u></h3>
<u>We </u><u>have</u><u>, </u>
- <u>The </u><u>perimeter </u><u>of </u><u>rectangle </u><u>is </u><u>2</u><u>8</u><u> </u><u>cm</u>
- <u>The </u><u>length </u><u>of </u><u>rectangle </u><u>is </u><u>8</u><u> </u><u>cm</u>
Let the breath of the rectangle be x
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Thus, The breath of the rectangle is 6 cm
<h3>
<u>Now</u><u>, </u></h3>
<u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>area </u><u>of </u><u>rectangle </u>
<u>We </u><u>know </u><u>that</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Area of rectangle
Hence, The breath and area of rectangle is 6cm and 48 cm² .
