Answer:
140
Step-by-step explanation:
Let the number be represented by x. You are given ...
(3/5)x = 42
Multiplying by 10/3 gives ...
(10/3)(3/5)x = (10/3)(42)
2x = 140 . . . . the value of twice the number

Answer:
56√2 ≈ 79.20
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length, so the side length here is ...
s·√2 = 28
s = 28/√2
The perimeter is 4 times the side length, so is ...
P = 4s = 4·28/√2
= 4·28·(√2)/2 . . . . . multiply by (√2)/(√2) to rationalize the denominator
= 56√2 ≈ 79.195959
The perimeter of the square is 56√2, about 79.20 units.
