Question

The expression 2(I+w) is used to calculate the perimeter of a rectangle, where I is length and w is width. If the length is2/5 unit and the width is 1/5 unit, what is the perimeter of the rectangle in units

Answer 1

Answer:

• 6/5 or 1.2 units

Step-by-step explanation:

Given:

• l = 2/5 units
• w = 1/5 units

Find the perimeter:

• P = 2(l + w)
• P = 2(2/5 + 1/5) = 2(3/5) = 6/5 or 1.2 units

Answer 2

• l=2/5
• w=1/5

Perimeter

• 2(l+w)
• 2(2/5+1/5)
• 2(3/5)
• 6/5 units
