Question

The perimeter of a rectangular garden
146 m. Its length is 4 m more than twice
it's breadth. What are the length and the
breadth of the garden?
​

Answer 1

Given,

☆The perimeter of rectangular garden is 146 m

☆ Let the breadth be x

☆ Then, the length is 2x + 4

Perimeter of rectangular garden = 2(l + b)

146 = 2(2x + 4 + x)

$\frac{146}{2}$ = 3x + 4

73 = 3x + 4

73 - 4 = 3x

69 = 3x

x = $\frac{69}{3}$

x = 23

Breadth = x = 23

Length = 2x + 4 = 2(23) + 4 = 46 + 4 = 50 m
