Mathematics Areas and perimeters

54.5 Sq. cm

Step-by-step explanation:

area of a right angled triangle = 1/ 2 × base × height

(here, the base is 8 and height is 6)

= 1/ 2 × 6 × 8

= 4 × 6

= 24 Sq. cm

area of a circle = r²

(r is the radius that is diameter/ 2, and the value of is 3. 14)

= 3. 14.× (5)²

= 3.14 × 25

= 78.5 Sq. cm

area of the shaded region = area of Circle - area of triangle

= 78.5 - 24

that is option 3

is means division by fractions
