A jewelry store uses boxes, as shown below, to package the jewelry they sell. The store plans to decorate the sides of the box, not the top and bottom. What is the area of the jewelry box that would need to be decorated?
lateral surface area: _cm squared

answer: 60%

explanation:

÷

= 60%

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
