Question

Roshni had 200 cm of lace. She stiched it around the border of 3 square handkerchiefs of equal size. Find the length of lace left with her if each side of square handkerchiefs measures 12 cm.​

Answer 1

Answer:

Your answer is 56 cm

Step-by-step explanation:

total length of the lace = 200 cm

in a square made of lace (perimeter of square) is = 4a

= 4 x 12

= 48 cm

for three handkerchiefs = 3 x 48

                                       = 144 cm

remaining amount of lace = total length - used lace for handkerchiefs

                                           = 200 - 144

                                           = 56 cm

remaining lace is 56 cm
