Answer 1

$\large\underline{\underline{\sf{\color{brown}{Question:}}}}$

Five square flower beds each of sides 1m are dug on a piece of land 5 m long and 4m wide . What is the area of the remaining part of the land?

$\large\underline{\underline{\sf{\green{Required \; Solution:}}}}$

Remaining area of land,

$\sf :\implies Area \; of \;rectangular\; land - Area \;of \;five \;flower\; beds$ $\sf{:\implies Area \; of \; rectangular \; lands - 5\times Area \;of \; square \; flower \; beds}$

Area of rectangular land,

                $:\implies \sf{ length\; of \;land }$ $=l= \sf 5 ~cm$

                $:\implies \sf Breath \; of \; land = b = 4 ~m$

Area of land,

                $:\implies l \times \sf b$

                $:\implies \sf 5 \times 4$

                $:\implies \sf 20~ sq. m$

                $:\implies \boxed{\pink{\sf {20~m^2}}}$

Area of square flower bed

Side of flower bed = a = 1 m

Area of flower bed $:\implies \sf a \times a$

                                 $:\implies \sf 1 \times 1$

                                 $:\implies \sf 1 ~sq.~m$

                                 $:\implies \boxed{\sf{\pink{1~m^2}}}$

Now,

Remaining area of land,

                        $\sf :\implies Area \; of \; rectangular \; land - 5 \times Area \; of \; square \; flower \; bed$

                        $:\implies \sf 20 - 5 \times 1$

                        $:\implies \sf 20 - 5$

                        $:\implies \boxed{\sf{\pink{15~m^2}}}$

$\sf{ \color{brown} {\therefore~ 15m^2 ~of ~the ~remaining~ besides}} \\\sf{\color{brown} {~flower ~beds.}}$
