Question

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 1

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
