Problema Solution

1.The width of a rectangular lot is 4 meters less than its length. If the perimeter of the lots is 76 meters, find the dimensions and the area of the lot.

Answer provided by our tutors

lenght= x

width= x-4

perimeter= 2(length +width)

76= 2(x+x-4)

38= 2x-4

42= 2x

x= 21.

so, length =21 cm, width = 17cm

so, dimension is 21 cm by 17 cm

area= 21*17 = 357 cm^2 is area....

done with the question.
