The length of a rectangle is (x+8) inches long and the width is 7 4/5 inches. if the area is 37 7/10 square inches. write an equation that could be used to find the length of the rectangle



Answer :

Area of a rectangle = width x length

Width = 7 4/5

Length = x+8

Area = 37 7/10

Replacing:

Area = width x length

Lenght = Area / width

x+8 = (37 7/10 ) / (7 4/5)

Solve for x:

x = [(37 7/10 ) / (7 4/5)] -8

Lenght = x+8 = ( [(37 7/10 ) / (7 4/5)] -8)+8 = [(area/ width)-8]+8
