A rectangular price tag has a perimeter of 28 centimeters. Its area is 40 square centimeters. What are the dimensions of the price tag?

10 x 4

Step-by-step explanation:

what factors are there for 40?

1, 2, 5, 8, 10, 20, 40

A rectangle has 2 equal long sides and 2 equal short sides. The area is the short times the long.

10 plus 10 and 4 plus 4 equals 28. 4 x 10 equals 40.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

you can use a^2+ b^2=c^2
