Answer:
- The dimensions of rectangle are 12 m and 4.5 m
Step-by-step explanation:
Given that, The length of a rectangle is 3 m more than twice the width, and the area of the rectangle is 54 m²
Let's assume width of rectangle be x m and length be 3 + 2x m respectively. To find the dimensions of the rectangle we will use the formula of Perimeter of rectangle
Substituting values in above formula:
Hence,
- Length of rectangle = 3 + 2x = 3 + 2(4.5) = 12 m
- Width of the rectangle = x = 4.5m
