1. perimeter 10(2)+10(2)=32+20

   perimeter = 52cm

   area=b times h

  area = 16(9)=144cm2

   

2 <em>TRAPEZOID</em>

<em>   </em>perimeter =( 21+24+25+44.67)m

                      =114.67m

                     area= 1/2( b1+b2)h

                                1/2(44.67+25)20

How long will it take 5000 to double in an account that pays 5.6% simple interest
Ganezh [65]
So... doubling 5000 is just 10,000, thus

\bf \qquad \textit{Simple Interest Earned Amount}\\\\&#10;A=P(1+rt)\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\to &\$10,000\\&#10;P=\textit{original amount deposited}\to& \$5,000\\&#10;r=rate\to 5.6\%\to \frac{5.6}{100}\to &0.056\\&#10;t=years&#10;\end{cases}&#10;\\\\\\&#10;10000=5000(1+0.056t)\implies \cfrac{10000}{5000}=1+0.056t&#10;\\\\\\&#10;2=1+0.056t\implies 1=0.056t\implies \cfrac{1}{0.056}=t
