The length of a rectangle is 5 times of its breadth. If the breadth is 10 cm, then what is the perimeter of the rectangle?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 120cm
Concept Used :
Perimeter of rectangle = 2(l + b)
Given :
Breadth, b = 10 cm.
Length is 5 times of breadth.
l = 5 × 10 = 50 cm
Now, perimeter = 2(l + b)
⇒ 2(50 + 10) = 2 × 60 = 120.
Hence the perimeter of the rectangle is 120 cm.
