Explain how area and perimeter are similar and different

Step-by-step explanation:

For example, if a rectangle has a length l = 15 m and breadth w = 10 m

Then,

The perimeter of rectangle = lenght l + breadth w + length l + breadth

                                            = l + w + l + w

                                            = 2l + 2w

                                            = 2(15) + 2(10)

                                            = 30 + 20

                                            = 50 m

The area of the rectangle = l × w

                                           = 15 × 10

                                           = 150 m²        

i am not sure :

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
