Answer:
Rectangle A: 6cm × 4cm
Rectangle B: 6cm × 2cm
Step-by-step explanation:
Area of square = side² = 36 cm²
Each side = 6 cm
When you cut a square to form rectangles, length is equal to the side of the square but the width changes.
Area of rectangle A = ⅔(36) = 24
Rectangle A: length = 6 cm
Area = 24 = length × width
24 = 6 × width
width = 4cm
Dimensions of A are 6×4
Area of rectangle B = ⅓(36) = 12
Rectangle B: length = 6 cm
Area = 12 = length × width
12 = 6 × width
width = 2 cm
Dimensions of B are 6×2
