An indoor sport exhibition is coming to the arena. Your supervisor has asked you to help set up a handball pitch and seating area as shown in the plan view below..Use the following formulae:Perimeter of a rectangle = 2l + 2wCircumference of a circle = πdπ = 3.14Area of a rectangle = lwArea of a circle = πr²What is the total perimeter of the pitch and seating area?mWhat is the total area of the pitch and seating area? m2

Answer:Perimeter: 174.8 mArea: 1,394 sq mStep-by-step explanation:First, the perimeter. Before we start, let's calculate the circumference of the half-circles at the ends of the field. The measurement says 2,000 cm, so let's convert it to 20 m for ease. Circumference of a circle: πd, where d = diameter.. in our case d = 20 m Circumference of a 20m diameter circle: 20π = 62.8 m We have 2 half circles... so the perimeter of each half-circle will be: 31.4 m We also have 800 cm measurement for the "height" of the seating areas... let's convert that in 8 m We also need to find out the space between the seating area...  We know the whole rectangular pitch is 40 m, then we have to subtract the width of both seating areas (20 and 15 m)... so the space between them is 5m So, starting with the upper left corner of the rectangular pitch, and working our way clockwise, we encounter the following lengths: P = 40 + 31.4 + 8 + 10 + 8 + 5 + 8 + 25 + 8 + 31.4 = 174.8 m The total perimeter is then of 174.8 m For the area, we need to calculate the area of all forms: Large rectangular pitch: LR = 40 x 20 = 800 sq m The two half circles, form a circle, so A = πr², where r is the radius, which is half the diameter. AC = π (10)² = 100 π = 314 sq m Then the seating areas: SA1 = 25 x 8 = 200 sq m SA2 = 10 x 8 - 80 sq m Then, we add up everything: TA = LR + AC + SA1 + SA2 TA = 800 + 314 + 200 + 80 = 1,394 sq m
