Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is m and the width of the patches is m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence, ≈ 90 such patches can be made out of the whole material. (Answer)

Answer: $10
Step-by-step explanation:
If weekly allowance is x
Half of it is x/2
Remaining half plus $7 is $12
x/2 + 7 = 12
Subtract by 7 both sides
x/2+7-7 = 12 - 7
x/2 = 5
Multiply both sides by 2
(x/2)*2 = 5*2
x = 10
