Alex is drawing rectangles with different areas on a centimetre grid. he can draw 3 different rectangles with an area of 12cm2.how many rectangles could alex draw with an area of 11cm2 ?

2.75 or 2

Step-by-step explanation:

Number of rectangles  could alex draw with an area of 11cm² = 1

Step-by-step explanation:

Minimum length in centimeter grid = 1 cm

Alex is drawing rectangles with different areas on a centimetre grid.He can draw 3 different rectangles with an area of 12cm²

That is

                     12 = 1 x 12

                     12 = 2 x 6

                     12 = 3 x 4

          These are the 3 different rectangles with an area of 12cm².

Now we need to find how many rectangles could alex draw with an area of 11cm².

                     11 = 1 x 11

So only one factorization is possible.

Number of rectangles  could alex draw with an area of 11cm² = 1

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
