Question

Seven square flower beds each of sides $0.8m$ are dug inside a park $3.2m$ wide and $5.6m$long.What is the area of the remaining part of the park $?$

• A. $17.92m^2$
• B. $13.44m^2$
• C. $4.48m^2$
• D. $2.56m^2$

Answer 1

The correct option is B

$13.44m^2$

Number of square flower beds$=7$

Sides of square flower beds$=0.8m$

Length of rectangular park$=5.6m$

Breadth of rectangular park$=3.2m$

Step 1: Finding the area of rectangular park

Area of rectangle$=$length $\times$bradth

$=5.6\times 3.2$

$=17.92m^2$

Step 2.:Finding the area of square flower bed

Area of square$=$side $\times$ side

Area of one square flower bed $=0.8\times 0.8$

$=0.64m^2$

Area of seven square flower bed$=7\times 0.64$

$=4.48m^2$

Step 3:Finding the area of remaining part

Area of remaining part$=$area of rectangular park $-$area of flower bed

$=17.92-4.48$

$=13.44m^2$

Hence, the area of remaining part of the rectangular park is $13.44m^2$
