Question

A rectangle is $22m$ long and $12m$ wide.From its four corners,quadrants of radius $2.5m$ have been cut. Find the area of the remaining part.

Answer 1

$4$ Quadrants of radius $2.5m$ is equivalent to 1 circle of $2.5cm$

Area of circle $=\pi (2.5{)}^3=6.25\pi m^2$

$=19.625m^2$

Area of rectangle = $22\times 12=264m^2$

$264-19.625=244.375m^2$
