Subtract the difference from the sum of the length and width, so to speak, equalize them.
27 – 3 = 24.
This is twice the width, divide by 2 and find the width of the straight line.
24: 2 = 12 – width
12 + 3 = 15 -length
The area is equal to the product of the sides.
S = 12 * 15 = 180 cm ^ 2
Answer: 180 cm ^ 2
