First, find the area (surface) of the ceiling. Since it is opposite the floor, it has the same length and width(A
= 1xw).19 feet x 10 feet = 190 square feet (ceiling) Next find the combined area of two matching (opposite) walls. Start with the walls formed by the length and height of the room.(Clear the decimal in the divisor.) 19 feet x 8 feet = 152 square feet (first wall) 152 feet x 2 = 304 square feet (matching walls) Then find the area of the walls formed by the width andheight of the room. 10 feet x 8 feet = 80 square feet (second wall)
80 feet x 2 = 160 square feet (matching walls) Finally, combine all surfaces to be painted. 190 + 304 + 160
= 654 square feet

If 1/4 inch represents 1 foot, then 3/4 inch will represent 3 feet, and 1/2 foot will be represented by one- half of 1/4 inch, or 1/8 inch. Thus,Vhfeet will be represented by 3/4 inch plus 1/8 inch.

There are 30 days in April, 31 days in May, and 30 days in June for a total of 91 days.
91 × 35 = 3185.

Divide 30 by 8 to determine that the security guard takes 3.75 minutes to walk one city block. Multiply 3.75 by 6, the number of blocks it takes tC.mplete the circuit, to arrive at 22.50, or 221/2 minutes.
