If a length of a square is 3.2 cm square what is the perimeter and area​
stiv31 [10]
Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:

P= 2L + 2W and A= L x W

P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)

P= 12.8 cm

A= 3.2 x 3.2
A= 10.24 cm^2

babymother [125]

Answer: price of the watch before the discount is £23.5825

Step-by-step explanation:

Let x represent the original price of the watch.

Jason went shopping he bought a watch and a pair of trainers for a total price of £53.55. This price includes 15% loyalty discount. The value of the discount is

15/100 × 53.55 = 8.0325

This means that the original cost of both items is

53.55 + 8.0325 = 61.5825

Before the discounts, the trainers were priced at £38. Therefore,

38 + x = 61.5825

x = 61.5825 - 38

x = 23.5825
