Answer:
L=10.326cm
P=31.30cm
Step-by-step explanation:
A=55=L*W
L=5+W
A = (5+W)(W) = 55
55=W^2 + 5W
0 = W^2 + 5W - 55
use quadratic formula
W = [-5 (+/-) sqrt(25-4(-55))]/2
W= 5.326 cm or W=-20.65, so W=5.326cm
L=5+5.326
=10.326cm
P=2W+2L
P=2(5.326) + 2(10.326)
=31.30 centimeters
Answer: (15*12.5)-(8*10)
107.5 is the area not covered by the rug
Step-by-step explanation:
Basically all you need to do is estimate what 32.7 x 2.8 is. If what you get is close to 91.56, then Tom's answer is reasonable. If what you get is not close to 91.56, then his answer is not reasonable. Do you know how to estimate by rounding?
