QUESTION:

A SQUARE plot has a 3m wide path surrounding it. If the area of the path is 132sq.m, find the area of the plot.

solution:

\purple { \sf {64m}^{2} }

GIVEN:

A square plot has a 3m wide path surrounding it. If the area of the path is 132sq.m

To find:

find the area of the plot?

step by step explanation:

area of the plot = x

given : area of the path = 132 sq.m

area of the path = area of LARGE square - area of small square.

\sf let  \: us \:  assume \:  small \:  square \:  as \:   {x}^{2}

\sf let  \: us \:  assume \: large\:  square \:  as \:   ({x + 6})^{2}

so:

\sf {x}^{2}  -  ({x + 6}^{2} ) = 132

\sf {x}^{2}   = ({x + 6}^{2} )  -  132

\sf \cancel{ {x}^{2}}   = \cancel{{x}^{2}  }  + 12x + 36-  132

\sf96 = 12x

\sf x =  8

therefore,

\red{ \sf area  \: of  \: small  \: plot = 8×8 ={64m}^{2}  }
