Question

The bredth of a rectangular park is x meter and lenght is 4 more than 3 times of breadth find the perimeter of rectangle

Answer 1

Given that,
Width = x

According to question
Length = 3* Width +4
= 3x +4

Perimeter = 2(Length +Width)
= 2[(3x+4) + (x)]
= 2(x+3x+4)
= 2(4x+4)
= 2 * 4 (x+1)
= 8(x+1)

Perimeter = 8(x+1) or 8x+8
