Question

length of a rectangular plot its breadth is decreased by 5 M and its perimeter is 142 then what will be dimension

Answer 1

Let the length be x meters

So, the breadth be (x - 5) meters

According to Question,

Perimeter of Rectangle = 142 m

2(length + breadth) = 142 m

⇒ 2(x + x - 5) = 142

⇒ 2x - 5 = 142 / 2

⇒ 2x - 5 = 71

⇒ 2x = 71 + 5

⇒ 2x = 76

⇒ x = 76 / 2

⇒ x = 38

Required Measurements »

Length = x = 38 m

Breadth = x - 5 = 38 - 5 = 33 m

Hence, the length and the breadth of the rectangle are 38 meters and 33 meters respectively.
