My apologies, Precious. I made an incorrect assumption in the previous response for 4.4. Let's correct it using the dimensions clearly visible in the image. 4.4 Step 1: Identify the components of the figure and their dimensions. The figure consists of a rectangular base and a semicircle on top. The vertical side of the rectangular part is 47 mm. The horizontal side of the rectangular part (bottom) is 36 mm. The diameter of the semicircle is the width of the rectangular part, which is 36 mm. Step 2: Calculate the perimeter. The perimeter consists of: • Two vertical sides of the rectangle: 47 mm + 47 mm • The bottom horizontal side of the rectangle: 36 mm • The arc length of the semicircle: (1)/(2) × × diameter The formula for the arc length of a semicircle is L = (1)/(2) d, where d is the diameter. Here, d = 36 mm. P = 47 mm + 47 mm + 36 mm + (1)/(2) (36 mm) P = 130 mm + 18 mm Using ≈ 3.14159: P ≈ 130 mm + 18 × 3.14159 mm P ≈ 130 mm + 56.54862 mm P ≈ 186.54862 mm Rounding to two decimal places: P ≈ 186.55 mm The perimeter of the figure is 186.55 mm.
