Question
The sides of a rectangle are in the ratio of 6 : 5 and its area is 750 sq.m. Find the perimeter of rectangle (in m).
Answer: Option B
:
B
Let 6x and 5x be the sides of a rectangle.
⇒6x×5x=750
⇒30x2=750
⇒x2=75030=25
⇒x=5
Length = 6x = 30m
Breadth = 5x = 25m
Perimeter = 2(l + b) = 2(30 + 25) = 110m
