2 m 50 cm
60 cm
60 cm
250​

Answer 1

Answer:

Answer:

• We know

1 m = 100 cm

Length of the table cloth = 1 m 50 cm = 1 × 100 cm + 50 cm = 100 cm + 50 cm = 150 cm Width of the table cloth = 50 cm Length of the boundary of the cloth = 150 + 50 + 150 + 50 = 400 cm = 4 m Working: 150150050+050400Thus, the length of lace needed for one table cloth is 4 m.

• Length of lace required for one table cloth = 4 m

Length of lace required for three table cloths = 4 m × 3 = 12 m

• Total length of the roll of lace = 100 m

Length of lace used in three table cloths = 12 m Length of lace left in the roll = 100 m − 12 m = 88 m Working: 100-012088Thus, 88 m of lace is left in the roll.

Answer 2

88 lais

Step-by-step explanation:

we know 1 m=100 cm 100+50=150,100+50=150 150 breath 50+50+150+150= 400

4×3 =12,100-12=88 ans
