Question

If the formula for the perimeter of a rectangle is P=2l+2w, then w can be expressed as a.w=p-2w/21 b.w=p-l/2 c.w=21-p/2 d.w=p-l/2

Answer 1

Answer:

W can be expressed as  P / 2 - l .

Step-by-step explanation:

Formula for the perimeter of a rectangle is given as P = 2l + 2w.

We have to find an another way to write w, according to the question.

Given,

= > P = 2l + 2w

= > P - 2l = 2l - 2l + 2w       { Adding - 2l on both sides }

= > P - 2l = 2w

= > ( P - 2l ) / 2 = 2w / 2       { Dividing both sides by 2 }

= > ( P - 2l ) / 2 = w

= > ( P / 2 ) - ( 2l / 2 ) = w

= > P / 2 - l = w

Hence w can be expressed as P / 2 - l , if P = 2l + 2w.

Answer 2

Answer:

The correct answer is  C. w =  P -2l/2

.

Step-by-step explanation:

You should subtract 2l from both sides first and then divide by 2.
