The base of a rectangle is 6 cm longer than its height the area of a rectangle is 91 cm² what is the perimeter of the rectangle? I need help immediately. Thank you in advance!!

the perimeter of the rectangle is 38 cm

Step-by-step explanation:

Let h represent the base of the rectangle.

The base of a rectangle is 6 cm longer than its height. This means that the base of the rectangle is

h + 6

The area of the rectangle is 91 cm²

This means that

h(h + 6) = 91

h² + 6h - 91 = 0

h² + 13h - 7h - 91 = 0

h(h + 13) - 7(h + 13) = 0

h - 7 = 0 or h + 13 = 0

h = 7 or h = - 13

Since the height cannot be negative, it means that h = 7 cm

The base is

h + 6 = 7 + 6

base = 13

Perimeter = 2( base + height)

Perimeter = 2(13 + 6) = 2 × 19

Perimeter = 38 cm

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
