The length and width of a rectangle are consecutive integers. if the area of the rectangle is 90cm^2 , what is the primeter of the triangle

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

you have 6 cupcakes

22.83 repeating

step-by-step explanation:
