Question

3. What is the perimeter of a rectangle if the width is 2 ½ inches and the length is 4.5 inches?

(show how you get your answer please)

Answer 1

Perimeter of the rectangle = 14 inches

Explanation:

Step(i):-

Given length of the rectangle = 4.5 inches

Given that the width of the rectangle =
`2(1)/(2) = (5)/(2) = 2.5` inches

The area of the rectangle = length × width

= 4.5 × 2.5

= 11.25 sq inches

Step(ii):-

Perimeter of the rectangle = 2( length + width)

= 2( 4.5 + 2.5)

= 14 inches

Final answer:-

Perimeter of the rectangle = 14 inches
