A rectangular building lot has a width of 52.5 ft and a length of 136 ft. Determine the area of this lot in square meters.

 A = l x w  = 16.006 m x 41.344 m = 661.75 m²

Explanation:

Conversion first to meters and then the question is easy

How many ft in a meter?   1ft = .304 m

52.5 ft = 52.5 ft  x .304m/ft = 16.006m

136 ft = 136 ft  x .304 m/ft =  41.344m

What is the equation to find the area of a rectangular lot?

A = l x w  = 16.006 m x 41.344 m = 661.75 m²

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
