Explanation:
let the length and breadth's ratio be 4x and 3x
Given,
area of rectangle = 192 in²
we know,
Area of rectangle = L × B/w
after inserting the values in the formula we got,
→ 4x × 3x = 192
→ 12x² = 192
→ x² = 192/12 = 16
→ x² = 16
→ x = √16 = 4
→ x = 4
therefore , length and breadth/width are,
length = 4x = 4×4 = 16
width = 3x = 3×4 = 12
hence length is 16 in. and width is 12in.
hope this answer helps you dear.....take care and may u have a great day ahead!
