Question

a childs desk is made so that the dimensions are 2/3 the dimensions of a full size adult desk supposed to top of the full-size test measures 54 inches long by 36 inches wide what is the perimeter and area of the top of the child's desk

Answer 1

The perimeter and area of the top of the child's desk are 120 inch and 864 inch² respectively.

Step-by-step explanation

Dimensions of the top of the adult's desk : Length = 54 inches and Width = 36 inches.

As the dimensions of the child's desk are
`(2)/(3)` of the dimensions of the adult desk, so....

Length of child's desk
`= 54*(2)/(3) = 36` inches and

Width of child's desk
`=36*(2)/(3)=24` inches.

So, the perimeter of the top of the child's desk
`=2(length+width)= 2(36+24)=120` inches.

and the area of the top of the child's desk
`=length*width=36*24=864` inch²
