Question

A rectangular tablecloth measures 84 in. by 60 in. What length of lace is required to trim the edges of the cloth?

Answer 1

We have to find perimeter

• L=84in
• B=60in

$\\ \sf\longmapsto Perimeter=2(L+B)$

$\\ \sf\longmapsto Perimeter=2(84+60)$

$\\ \sf\longmapsto Perimeter=2(144)$

$\\ \sf\longmapsto Perimeter=288in$

Answer 2

Answer:

$288 \: \: in$

x

Step-by-step explanation:

To find the length of the lace we have to simply find the perimeter of the table cloth.

Formula to to find the perimeter of a rectangle is,

$perimeter = 2(length + width)$

In this question , they have already given the length and the width of the table cloth

Length = 84 in

Width = 60in

Let's solve now

$p = 2(l + w) \\ = 2(84 + 60) \\ = 2 \times 144 \\ = 288 \: in$

Hope this helps you.
