Answer:
Step-by-step explanation:
Let length and width of a rectangle be x, x+1
Area = 90 sq.cm
length * width = 90
x * (x + 1) = 90
x² + x = 90
x² + x - 90 = 0
x² + 10x - 9x - 9 * 10 = 0
x ( x + 10 ) - 9 (x + 10 ) = 0
(x + 10 ) (x - 9) = 0
x + 10 = 0 or x - 9 = 0
x = -10 { impossible . as length cannot be negative} ;
x = 9
Length = 9 , width = 10
Its as simple as length times breath there for it is 7/9 times 6/5 which has a common denominator of 45 so now it is 7/45 and 6/45 and then we say how many times did we multiply the denominator to get to 45 and use that number to multiply the numerator so now we have 35/45 and 54/45 and if you times both of them together you get 14/15 as a final answere
