Question

its urgent
calculate The area of the shaded region....

Answer 1

Answer:

g) 98.5 $cm^{2}$

h) 153.36$cm^{2}$

Step-by-step explanation:

g)Area of shaded region= Area of rectangle-Area of two triangles

Area of rectangle=11X13=143cm$cm^{2}$

Area of Ist triangle=$\frac{1}{2}bh=\frac{1}{2} 11*5$=55/2=22.5$cm^{2}$

Area of IInd triangle=$\frac{1}{2}bh=\frac{1}{2} 11*4$=44/2=22$cm^{2}$

Area of shaded region=143-[22.5+22]=98.5$cm^{2}$

h)Area of shaded region= Area of circle-Area of rectangle

Area of circle=$\pi r^{2} =\pi* 8*8=3.14*64=200.96 cm^{2}</p><p> [80 mm=80/10 cm]$

Area of rectangle=5.6*8.5=47.6$cm^{2}$

Area of shaded region=200.96-47.6=153.36$cm^{2}$
