The floor of a shed has an area of 99 square feet. the floor is in the shape of a rectangle whose length is 7 feet less than twice the width. find the length and the width of the floor of the shed. use the formula, area equals=length times•width.

W=width, L=length
L=2W-7
LxW=99  (now substitute)
(2W-7)xW=99 (distribute W)
2W²-7W=99
2W²-7W-99=0  (set to 0 to solve)
(W-18/2)(W+9/2)=0
(W-9)(2W+9)=0
W-9=0; W=9
2W+9=0; 2w=(-9) not possible in real world to have a negative length
So, width = 9 ft, and length = 2(9)-7 = 11 ft

The first solid's volume is 15/16 or 0.9375. The second solid's volume is 7/4, 1 3/4, or 1.75.

Step-by-step explanation:

First Solid

V= l*w*h

V= 5/8*3/4*2

V= 15/16

15/16 as a decimal is 0.9375

Second Solid

V= l*w*h

V= 6*7/12*1/2

V=  7/4

7/4 as a mixed fraction is 1 3/4. 7/4 as a decimal is 1.75.
