\huge{\mathcal{Given :}}

  • Breadth = 15m
  • Perimeter = 90m

\huge{\mathcal{To \: Find :}}

  • The length of the rectangle.

\huge{\mathcal{Solution :}}

As we know,

\boxed{\sf{Perimeter = 2 × (Length + Breadth) }}

Let the length be x.

ATQ,

↪ 90m = 2 ×( x + 15m) \\\ ↪ 90m = 2x + 30m \\\ ↪ 90m - 30m = 2x \\\ ↪ 60m = 2x \\\ ↪ 60m ÷ 2 = x \\\ ↪ x = 30m

Hence, length of the rectangle is 30m.
