The area of a rectangle is 30 square inches and one side is 12 inches long. Find the perimeter of the rectangle

31 is the perimeter

Step-by-step explanation:

Since you already know that two side lengths are 12 you have to add thhem together to get 24.

Now you know that the area is 30 sq inches so you would have to find a number that equals 30/12 which equals 2.5

2.5 times 12 equals 30

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
