Question

A rectangle has length represented as (R +5) and width represented as (R + 2).

Answer 1

Answer:

4(R + 5 + R + 2) [Option B]

Step-by-step explanation:

GIVEN :-

• Length = R + 5
• Width = R + 2

TO FIND :-

• Perimeter of the rectangle

FORMULAE TO BE USED :-

For a rectangle with length 'l' and width 'w' , its perimeter = 4(l + w)

SOLUTION :-

Perimeter = $4(R + 5 + R+2)$

                 = $4(2R + 7)$

                 = $8R + 14$
