First, convert 18,900 cm² into m²
18,900 cm x
x
= 1.89 m²
A = L x w
1.89 = L x 1.8
1.05 = L
Answer: 1.05 m
Perimeter
P = 2L + 2w
= 2(32.5) + 2(18.4)
= 65 + 36.8
= 101.8
Answer: 101.8 m
Area
Area of Seating section = Area of big rectangle - area of small rectangle
A = (32.5 x 18.4) - (28 x 15)
= 598 - 420
= 178
Answer: 178 m
