Problema Solution

a rectangular cloth is 75.5 cm long and 53.75 cm wide. how much lace is needed to sew around it, allowing 1.5 cm for the overlap?

Answer provided by our tutors

Let


l = 75.5 cm is the length of the rectangular cloth

w = 53.75 cm width of the rectangular cloth

w1 = 1.5 cm the width of the lace needs to be equal to the overlap

l1 = the length of the lace it is equal to the perimeter of the rectangle


l1 = 2*(l + w)

l1 = 2*(75.5 + 53.75)


l1 = 258.5 cm


We need to find the area of the lace. The lace is also rectangular surface so its area is l1 * w1 that is


l1 * w1 = 258.5 * 1.5 = 387.75 cm^2 lace


We need 387.75 cm^2 lace.
