On a bicycle trail, the city is painting arrows like the one shown below:
calculate the area of the arrow by decomposing it into rectangles and triangles.
66.5 square centimeters
69.5 square centimeters
83 square centimeters
99 square centimeters

Base of the triangle is 9cm and height is 11-8 = 3cm. Area of triangle= 1/2 x base x height = 1/2 x 9 x 3= 13.5cm^2. Length of the rectangle is 7cm and width is 8cm. Area of rectangle = length x width = 7x8 = 56. Now add both the areas to get area of an arrow = 13.5 + 56 = 69.5square centimeters.
