Question

semi circular lawns for attached to all ages of a rectangular field measuring 24 metre into 35 metre find the area of the total field ​

Answer 1

Answer:

Area of the total field ​is 2254.49 $m^2$

Step-by-step explanation:

Area of the rectangular field$l\times b=24\times 35=840 m^2$

Area of the semi circular lawns of 24 meter length is

$A_{1} =\frac{\pi r^2}{2} \\=\frac{\pi 12^2}{2}\\=226.19 m^{2}$

Area of the semi circular lawns of 35 meter length is

$A_{2} =\frac{\pi r^2}{2} \\=\frac{\pi 17.5^2}{2}\\=481.05 m^{2}$

Area field is= Area of rectangle+ 2 times the area of the semi circle of 24 side+2 times the area of the semi circle of 35 side

=$840+2\times 226.19+2\times 481.05\\ =2254.49 m^2$

Area of the total field ​is 2254.49 $m^2$
