Q1 .A rectangular piece of land measures \"L=0.8dm\" by \"W=.5dm\" \r
\n" ); document.write( "\n" ); document.write( "it is to be fenced with \"four\" lines of wire
\n" ); document.write( "the length of wire that is needed is equal \"four\" times the perimeter of a rectangular piece of land\r
\n" ); document.write( "\n" ); document.write( "if land measures \"L=0.8dm\" by \"W=.5dm\", perimeter is \"P=2%280.8dm%2B0.5dm%29\"
\n" ); document.write( "\"P=2%281.3dm%29\"
\n" ); document.write( "\"P=2.6dm\"\r
\n" ); document.write( "\n" ); document.write( "\"four\" times the perimeter is:\"4%2A2.6dm=10.4dm\"-the length of wire that is needed \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Q2. A rectangular garden is \"105m\" by \"75m\". \r
\n" ); document.write( "\n" ); document.write( "how many round of this garden will a boy make, if he runs \"3600m\" \r
\n" ); document.write( "\n" ); document.write( "divide \"3600m\" by perimeter\r
\n" ); document.write( "\n" ); document.write( "\"P=2%28105m%2B75m%29\"\r
\n" ); document.write( "\n" ); document.write( "\"P=2%28180m%29\"\r
\n" ); document.write( "\n" ); document.write( "\"P=360m\"\r
\n" ); document.write( "\n" ); document.write( "\"360cross%280%29cross%28m%29%2F36cross%280%29cross%28m%29=360%2F36=10\" \r

\n" ); document.write( "\n" ); document.write( "Q3. Find the perimeter of square equal in area to two squares whose sides are \"12m\" and \"5m\" respectively.\r
\n" ); document.write( "\n" ); document.write( "We know perimeter of square \"A=+4%28side%29\"\r
\n" ); document.write( "\n" ); document.write( "So side of first square is \"+12m\" and area is \"+12m%2A12m=144m%5E2\"
\n" ); document.write( "Side of second square is \"5m\"and area is \"+5m%2A5m=25m%5E2\" \r
\n" ); document.write( "\n" ); document.write( "the area of both is \"++144%2B25=169m%5E2\"\r
\n" ); document.write( "\n" ); document.write( "Area of third square is equal to the area of both squares above, so,the area of third square is \"++169m%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So side of third square = \"13m\" [because \"13m%2A13m=169m%5E2\"]\r
