A square of area 36 cm2 is cut to make two rectangles, A and B the ratio of A to area b is 2 : 1

24 cm² and 12 cm²

Step-by-step explanation:

Sum the parts of the ratio, 2 + 1 = 3 parts

Divide the area by 3 to find the value of one part of the ratio.

36 cm² : 3 = 12 cm² ← value of 1 part of the ratio, thus

2 parts = 2 * 12 = 24 cm²

area of A = 12 cm² and area of B = 24 cm²
