Question

At Carter's birthday party his mom made a cake in a rectangular shape. The length of cake is 8 cm and width of cake is 6 cm. If she wants to add 1 cm of cream around the cake, what will be the perimeter and area of the rectangle cake?

Answer 1

The perimeter will be 36cm as length and bredth increases by 2cm. So the area will be 160cm^2.

Answer 2

Perimeter of rectangular cake = 36 cm

Area of rectangular cake is 80 square cm.

Explanation:

Length of the cake = 8 cm

Width of cake = 6 cm

Since we are given that she wants to add 1 cm of cream around the cake

So, Length becomes: 8+1+1 =10 cm

Width becomes: 6+1+1= 8 cm

Perimeter of rectangular cake =
`2(Length+Breadth)`

=
`2(10+8)`

=
`2(18)`

=
`36`

Thus the perimeter of rectangular cake = 36 cm

Area of rectangular cake =
`Length * Breath`

=
`10 * 8`

=
`80cm^2`

Thus the area of rectangular cake is 80 square cm.
