Question

A rectangular ground $9.8m$ long and $6.5m$ wide, has four square planters each of side $70cm$ . Find the area of the remaining ground.

Answer 1

Length of the rectangular ground$=l=9.8$m

Breadth of the rectangular ground$=b=6.5$m

Area of the rectangular ground$=l\times b=9.8\times 6.5=63.7$sq.m

Side of square planter$=70$cm

Area of the planter$=side\times side=70\times 70=4900{cm}^2=\frac{4900}{100\times 100}{m}^2=0.49m^2$

$\because$ there are $4$ such planters.

$\therefore$ total area covered by the planters$=0.49\times 5=1.96m^2$

$\therefore$Area remaining$=63.7-1.96=61.74m^2$
