Question

A rectangle's length and width are in a ratio of 8:3. The area is 384 square millimeters. What are the length and width?

Answer 1

Let, the length = 8x
width = 3x
Now, 8x * 3x = 384
24x² = 384
x² = 384/24
x² = 16
x = √16
x = 4

So, length = 8(4) = 32 & Width = 3(4) = 12

It's dimension would be 32 × 12 mm

Hope this helps!
