A rectangle has an area of 30 square units and a perimeter of 34 meters.what are the dimensions of this rectangle
enyata [817]
P=2L+2W
A=WL

Therefore, if P=34, and A=30, then let us find the factors of 30 that could give a sum of half of the perimeter which is 34. Therefore:

P=2*15+2*2
A=15*2

P=34
A=30

Therefore, the dimensions of this rectangle are 15 and 2.

Answer:

option A

Step-by-step explanation:

the statement tell us that she slides the triangle 2 units down, so the vertical axis is the one that we are going to modify

we have the points: (1,2), (3,3) and (4,1)

so to these points we subtract "2" to the variable Y

I mean:

(1,2):   2-2=0

(3,3):    3-2=1

(4,1):    1-2=-1

finally we have:

(1,0), (3,1) and (4,-1)

A cylindrical container that contains three tennis balls that are 5.4 inches in diameter is lying on its side and passes through an x-ray scanner that scans from the top only.

When light is fall on the cylinder then its projection will be a rectangle.
