1.	the length of a rectangle plot exceeds its beeadth by 5m . if the perimeter of the plot is 142m . find the dimensions of the plot
Answer» ANSWER: ok Step-by-step explanation: let the breadth be X then, length = x + 5 perimeter = 2 ×( l + b) = 2 ×{x + ( x + 5)} = 2 ×{2x +5} = 4X + 10 Also, perimeter = 142cm so, 4x + 10 = 142cm 4x = 142cm - 10 4x = 132CM x = 132cm/4 x = 33cm hence, breadth = 33cm and length = x + 5 = 33 + 5 =38cm

the length of a rectangle plot exceeds its beeadth by 5m . if the perimeter of the plot is 142m . find the dimensions of the plot

Answer»

Step-by-step explanation:

let the breadth be X

then, length = x + 5

perimeter = 2 ×( l + b)

= 2 ×{x + ( x + 5)}

= 2 ×{2x +5}

= 4X + 10

Also, perimeter = 142cm

so, 4x + 10 = 142cm

4x = 142cm - 10

x = 132cm/4

x = 33cm

hence, breadth = 33cm and length = x + 5 = 33 + 5 =38cm
