Answer:
breadth = 11 cm
length = 25 cm
Step-by-step explanation:
Let 'b' be the breadth of the rectangle
Given,
l = 3 + 2b
P = 72 cm
We know that,
2( l + b ) = P
2 ( 3 + 2b + b ) = 72
2 ( 3 + 3b ) = 72
6 + 6b = 72
72 - 6 = 6b
66 = 6b
b = 66/6 = 11 cm
∴ Breadth = b = 11 cm
Length = l = 3 + 2b = 3 + 2(11) = 25 cm//
