1- 26 × (– 48) + (– 48) × (–36)
(– 48) [ 26 +(–36) ]
(– 48) × [-10]
= 480
2- Starting position of mine shaft is = 10m above ground
but,
it moves in opposite direction so it travels the distance (-350 m ) below the ground.
Total distance covered by mine shaft = 10m - (-350m)
= 10 + 350
= 360m
Now, taken to cover a distance of 6m by it = 1 minute
Time taken to cover a distance of 1m by it = \frac{1}{6\ }\min
6
1
min
Therefore, tie taken to a cover a distance of 360m = \frac{1}{6}\times\ 360\ =\ 60\ \min\ \

× 360 = 60 min
60 minutes = 1 hour
thus, in one hour the mine shraft reaches = 350 below the ground.
3. The sheet of paper is 12 1/2 cm long and 10 2/3 cm wide. Or
the length = 25/2 cm and the width = 32/3 cm.
The perimeter of the sheet of paper = 2[(25/2) + (32/3)]
= 2[75+64]/6
= 2*139/6
= 46.33 or 46 1/3 cm. Answer.
Its area = (25/2)(32/3) = 133.33 or 133 1/3 sq.cm. Answer.
