First, find the area of the tiles. 6 in. * 13 in. = 78 in^2.
Then divide the area of the floor by the area of the tiles.
8500 / 78 = 108 38/39
Answer:
1st option is correct
Step-by-step explanation:
(2x^2 -5y)/(3x-y)
((2*2)^2-(5*-4))/((3*-4)-(-4))
(4^2+20)/(-12+4)
36/-8
-4.5
Answer:
130/l in where l is the length of the rectangle
Step-by-step explanation:
The formula for area of a rectangle is length by width where the width is the height of the rectangle
Given that area=130 in²
Lets assume the length of this rectangle is =l inches
Then ;
A=l*w
130 =l*w
130/l = w
130/l in = height
Answer:
The length of the rectangular atrium is 88 inches and the width is 22 inches
Step-by-step explanation:
Let
x ----> the length of the rectangular atrium
y ----> the width of the rectangular atrium
we know that
The perimeter of the rectangular atrium is


so

Simplify
----> equation A
-----> equation B
substitute equation B in equation A and solve for y


Divide by 5 both sides

Find the value of x

therefore
The length of the rectangular atrium is 88 inches and the width is 22 inches
