Question

The shape of a garden is rectangular in the middle and semi-circular at the ends. Find the area and the perimeter of this garden.

Answer 1

Radius of semi-circular $=5/2$cm

so ength of reactangular $=30-2\left(5/2\right)$

$=25$m

Breadth of reactangle $=5$m

Area $(l\times b)+2\left(\frac{\pi r^2}{2}\right)$

$=(25\times 5)+\left(\pi \right){\left(\frac{5}{2}\right)}^2=144.625$m

Perimter $=2\left(\pi r\right)+2l$

$=15.7+50$

$=65.7$m.
