Question

The length of a rectangle is three mes is bread
1875 sq om, find its perimeter​

Answer 1

Answer:

200m

Step-by-step explanation:

$let \: breadth = x \\ then \: length = 3x \\ \\ as \: per \: the \: question \\ = > area = 1875 \\ \\ = > 3x \times x = 1875 \\ \\ = > 3 {x}^{2} = 1875 \\ \\ = > {x}^{2} = 625 \\ \\ = > x = \sqrt{625} \\ \\ = > x = 25 \: m \\ \\ length = 3x = 3 \times 25 = 75 \: \\ breadth = 25 \: m \\ \\ perimeter \\= 2(75 + 25)\\ = 2 \times 100 \\= 200 \: m$
