Question

To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.

This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)

Answer 1

given length [l]=30

width[w]=75

perimeter= 2 (l + w )=2(30+75)=210

so

answer is A.210

Answer 2

• 210 (A)

Explanation:

Use the formula:

• P = 2(l + w)

Substitute the values and find P:

• P = 2(30 +75) = 2(105) = 210

Correct choice is A
