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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
