First you need to find the sum of the length and width of this rectangle.
We divide the specified perimeter into 2 equal parts.
270/2 = 135 cm.
Since we know that the width of the rectangle is 45 cm, then its length will be equal to the difference between the sum of the sides and the width.
135 – 45 = 90 cm.
To find the area of a rectangle, multiply the length by the width.
90 * 45 = 4050 cm2
Answer: The area of the rectangle is 4050 cm2
