P = 2L + 2W
A = LW
Perimeter is given so we will use
The perimeter of a rectangle = 2*length + 2*width
Let suppose the width = x
Length = twice the width = 2x
the Perimeter = 72 = 2*2x + 2*x
72 = 4x + 2x
Now we have 72 = 6x, then dividing both sides by 6we get x = 12
So,
Width = 12 cm
Length is 12 x 2 = 24 cm

Answer:
Total weight = 70.5 kg
Step-by-step explanation:
Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.
2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each
2 pieces from the width of the rectangular frame, hence, they a length of 5 m each
To find the length of the diagonal, we can use Pythagoras Theorem:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 12²
Hypotenuse² = 169²
Hypotenuse = 13
Hence, the length of the piece of metal placed at the diagonal is 13cm
Find the sum of all lengths of the metal pieces.
Total length = 12 + 12 + 5 + 5 + 13
Total length = 47 m
Total weight = 1.5 × Total length
Total weight = 1.5 kg/m × 47m
Total weight = 70.5 kg
10p + 5 = 18p - 62 (Given)
10p = 18p - 67 (Subtract 5 from both sides)
-8p = -67 (Subtract 18p from both sides)
p = 8.375 (Divide both sides by -8)
