Dimensions of factory = length: 210 ft, width: 140 ft
Step-by-step explanation:
The total area of the lot can be calculated as:
Since, the area of factory should be equal to area of lawn:
Now, let 'x' be the width of lawn, the dimensions of factory can be written as:
Since, area is equal to length x width:
Divide whole equation by 4,
Solving above quadratic equation, we get,
x = 35 seems realistic width of the lawn.
Now, finding the dimension of factory:
We can also reconfirm the area of factory by multiplying the above two lengths:
140 * 210 = 29400 ft
