Question

John needs to wrap the edge of his rectangular desk with duct tape He knows the width is 10/8 of a meter and the length of a meter How much duct tape does he need to wrap the desks perimeter

Answer 1

13/4 m or 3.25 meters

1) Given the width is 10/8 meter

The length is 3/8 meter

2) To wrap the rectangular desk let's use this formula, for the Perimeter (2p):

2p= 2(w+l) Plug into w and l the measures

2p = 2(3/8 +10/8) Proceed with the sum within the parentheses

2p = 2(13/8) Distribute the factor

2p =13/4

3) Hence, the perimeter is 13/4 or 3.25 meters
