Question

A rectangle with an area of 324 square meters has a length and width in a ratio of 4:1. What are the length and width?

Answer 1

Here, 4x * x = 324
Now, we need to calculate that unit of x value as follows:
4x * x = 324
4x² = 324
x² = 324/4
x² = 81
x = √81
x = 9
So, 4x = 4(9) = 36

So, dimensions of rectangle would be: 36 × 9

Hope this helps!
