Question

the length of a rectangle is one more than twice its breadth if the perimeter of a rectangle is 44 cm find its dimensions

Answer 1

Let breadth = x
A.T.Q
Length = 2x+1
Given that Perimeter equals 44
2(l+b) = 44
2(2x+1+x)= 44
2(3x+1)= 44
6x+2= 44
6x= 42
x =7
Breadth which was x equals 7
Length equals 2x+1 equals 15
