  1. Answer :-

    • Ratio = 13 : 10 [option A]

    Given :-

    • Area of rectangular plot increased by 30%

    To find :-

    • Ratio between new and original rectangle

    Explanation :-

    Let the Original rectangle’s area = y

    New rectangle area = (100 + increased percentage) of original rectangle

    [tex]\longmapsto\rm \bigg(100 + 30\bigg) \times y[/tex]

    [tex]\longmapsto\rm \dfrac{100 + 30}{100} \times y[/tex]

    [tex]\longmapsto\rm \dfrac{130}{100}\times y[/tex]

    [tex]\longmapsto\bf \dfrac{13}{10}y[/tex]

    Finding ratio,

    [tex]\longmapsto\rm \dfrac{13}{10}y = y[/tex]

    [tex]\longmapsto\rm 13y = 10\times y[/tex]

    [tex]\longmapsto\rm 13y = 10y[/tex]

    [tex] \red {\underline {\boxed{ \bf \longmapsto 13 =10 }}}[/tex]

    Hence, the ratio between new rectangle and the original rectangle = 13 : 10 [Option A].

  2. Answer:

    If the area of a rectangular plot increase by 30% while its breadth remains same what will be the ratio of the areas of new and old figures ?

    Explanation

    Let original length = x and original breadth = y. ∴ Required ratio = (13xy10xy)=1310 = 13 : 10.

    is it useful
