The end of a house has the shape of a square surmounted by an equilateral triangle. if the length of the base is measured to be 33 feet, with a maximum error in measurement of 1 inch, calculate the area of the end. (round your answer to two decimal places.)

1560.55 ft

Step-by-step explanation:

Both the sides of equilateral triangle and square are represented by x as shown in the sketch (attached). The height of equilateral triangle will be given by

Area of rectangle=

Area of square=x*x=x^{2}

Total area is

Total area is and substituting x with 33 ft we obtain
