Question

square and a rectangular plot of land have the same perimeter the square has a side of 30 the rectangle is of breadth 1.5 dam.find the areas of the two plots​

Answer 1

$perimeterofsquare = 4 \times side \\ 30 = 4 \times side \\ side \: of \: square = 7.5 \\ area \: ofsquare = {s}^{2} = {7.5 }^{2} \\ = 56.25 \\ perimeter \: of \: reclangle = 2(l \\ + b ) \\ 30 = 2( l + 1.5) \\ 30 = 2l + 3 \\ l = 13.5 \\ area \: of \: rectange = l \times b \\ = 1.5 \times 13.5 \\ = 20.25$
