Question

Identify the area of the figure rounded to the nearest tenth.

Answer 1

91.5
`cm^(2)`

Explanation:

The area of the rectangle:

a = lw

a =(21)(3) = 63

The area of the square:

a = lw

a = (5)(5) = 25

The area of a half circle:

a=
`(\pi r^(2) )/(2)`

a=
`(3.14(1.5^(2)) )/(2)`

a =
`(3.14(2.25))/(2)`

a =
`(7.065)/(2)`

a = 3.5 rounded to the nearest tenth

63 + 25 + 3.5 =91.5
