Solution:
Area of rectangle = 93.6 m2
breadth = 3.6 m
Area of rectangle = l x b
⇒ 93.6 = l x 3.6
∴ l = 93.6 ÷ 3.6 = \(\frac { 936 }{ 10 }\) ÷ \(\frac { 36 }{ 10 }\)
= \(\frac { 936 }{ 10 }\) x \(\frac { 10 }{ 36 }\) = \(\frac { 936 }{ 36 }\) = 26 m
Perimeter of (RBSESolutions.com) rectangle 2(l + b)
= 2 (26 + 3.6)
= 2 x 29.6
= 59.2 m
