## Elementary Technical Mathematics

The lawn consists of 3 rectangular areas. Determine the width and length of each to find the area in square feet. The top rectangle measures 60 ft x 100 ft. $A=60\times 100=6000\ ft^2$ The middle rectangle measures 120 ft (60 ft + 60 ft) x 105 ft. $A=120\times 105=12600\ ft^2$ The lower rectangle measures 240 ft (120 ft + 60 ft + 60 ft) x 555 ft. $A=240\times 55=13200\ ft^2$ Sum to find the total area of the lawn. $6000+12600+13200=31800\ ft^2$ The problem requests the area be expressed in tsf (thousand square feet). Divide to convert. $31800\div1000=31.8 tsf$
