Answer:

area = (96 + 8π) m². perimeter = (35.3 + 4π) m

Explanation:

shape is made up of a semicircle and a trapezium.

Area of circle = π r ².

Circumference = π X D (D = diameter = 2 X radius).

Area of trapezium = ½ X (sum of parallel sides) X distance between them.

area of semicircle = 1/2 X π (4)² = 8π (m²).

area of trapezium = 1/2 (16 + 8) 8 = 96 m².

total area = (96 + 8π) m².

perimeter = 11.3 + 8 (on bottom) + 8 (on side) + 8 (on top) + 1/2π (8)

= (35.3 + 4π) m.
