$\text{Let the side of square 1, square 2 and square 3 be x, y and z respectively.}\\\\\text{Given that,}\\\\\text{Perimeter of square 1,~~ p =100 units.}\\\\\text{So}~ x=\dfrac p 4 = \dfrac{100}4 =25~\text{units.}\\\\\\\text{Area of square 2, a = 225 units}^2\\\\\text{So}~y = \sqrt{a} = \sqrt {225} = 15~ \text{units.}\\\\\text{Use Pythagorean theorem to find z}^2\\\\x^2 =y^2 +z^2 \\\\\implies 25^2 = 15^2 +z^2\\\\\implies z^2 = 625 - 225 = 400\\\\\\$

$\text{Hence the area of square 3 is 400 units}^2.$

the length of this prism is multiplied by a scale factor of 1/2 to create rectangular prism B the volume of rectangular prism B

anastassius [24]

We know that

[volume of rectangular prism]=L*W*h
L= 6 in prism A
volume of rectangular prism A=6*w*h

L=6*(1/2)------> L=3 in prism B

volume of rectangular prism B=3*w*h
so
volume of rectangular prism B=[volume of rectangular prism A]/2

the answer is
Volume of B is 1/2 volume of A
