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.
