Question

A rectangular lot measures 122ft by 57ft. A rectangular building measuring 22ft by 43ft is going to be built on the lot. The area of the lot that is not covered by the building will be covered with asphalt that costs $3 per square foot. What is the cost for the asphalt needed to do the job? 

Answer 1

A rectangular lot measures 122ft by 57ft

 

Area of rectangular lot = 122* 57=6954 ft^2

 

A rectangular building measuring 22ft by 43ft 

 

Area of building = 22*43=946 ft^2

 

The area of the lot that is not covered by the building=A rectangular lot - Area of building

                                                                         

                                                                            =6954 - 946

                                                                             =6008 ft^2

 

asphalt that costs $3 per square foot.

Cost for the asphalt = 6008* 3=18024

 

cost for the asphalt = $18,024
