Question

The perimeter of a rectangular field is 1000m. If the length is given as x, find the width in terms of x

Answer 1

Answer:

y = 500 - x

Step-by-step explanation:

• length l = x
• width b = ? let width is y

perimeter of rectangular = 2(l+b)

• 1000 = 2(x+y)
• 1000 = 2x+2y
• 1000 - 2x = 2y
• (1000 - 2x) /2 = y
• y = 500 - x ....Ans.

Answer 2

Answer:

length is given as X.

formula of perimeter of rectangle is,

perimeter=2(length+width)

1000=2(X+width)

1000/2=x+width

500=X+width

width=(500-x)m
