Question

fing the perimeter and area of the shaded region in the given figure​

Answer 1

Answer:

20

Step-by-step explanation:

hypotenuse^2=perpendicular^2+base^2

h^2=144+256=400

h=20

Answer 2

Answer:

508 cm^2

Step-by-step explanation

TAKE RIGHT ANGLED TRIANGLE ABC

AB=12CM

BC=16CM

AC=?

AC^2 = AB^2 + BC ^2

IF WE SOLVE THE ABOVE WE GET 20 CM

AREA OF TRIANGLE =1/2×B×h

it is a right angle triangle so h = 16cm

base = 12 cm

AREA =96 CM^2

perimeter =48cm

AREA OF SEMICIRCLE =PIE ×r^2 /2

r=20CM

area=628cm^2

perimeter = pie × r =62.8 cm

shaded area = 628 -96 =532 cm^2

shaded perimeter =14.8cm
