300 days of work.
Step-by-step explanation:
He needs to work for 300 days for 2 dollars a day to get 600 dollars:
300 x 2 = 600
Split this figure into 3 shapes: 2 triangles and 1 trapezoid
Area of top triangle = 1/2(7)(2) = 7 square units
Area of bottom triangle = 1/2(3)(7) = 10.5 square units
Area of trapezoid = 1/2(3 + 6)(4) = 18 square units
Area of the polygon = 7 + 10.5 + 18 = 35.5 square units
You have said that Brigitte is shorter than 5 feet. Translating your statement into rigorous mathematical terminology, we would write "Brigitte's height is less than 5 feet.". Then, using 'h' to represent Brigitte's height, and '<' to represent the words "less than", we can write the statement symbolically as [ h < 5 feet ].
Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
