Answer:
6 pieces.
Step-by-step explanation:
3/4 divided by 1/8
= 3/4 / 1/8
Invert the 1/8 and multiply:
= 3/4 * 8/1
= 24/4
= 6.
Dimensions of the rectangle (width and length) are 19 cm and 31 cm respectively.
Step-by-step explanation:
- Step 1: Given that the perimeter = 100 cm, let width be x cm and then length = 12 + x.
Perimeter of a rectangle = 2(length + width)
100 = 2(x + 12 + x)
100 = 4x + 24
4x = 100 - 24 = 76
∴ x = 76/4 = 19 cm
∴ Length = 19 + 12 = 31 cm
Answer:
45.45
Step-by-step explanation:
