What is the length and width of a room that is 60 square meters and has a perimeter of 32 meters
AleksAgata [21]
L = lenght
W = width

L * W = 60 \\
2L + 2W=32\\\\
L = \frac{32-2W}{2}\\
\frac{32-2W}{2}*W = 60\\
(16-W)*W = 60\\
-W^{2} + 16W -60 = 0\\\\

d = 16^{2} - 4*1*60 =  256 - 240 = 16 \\\\
W1 = \frac{-16+\sqrt{16}}{-2} =  \frac{-12}{-2} = 6\\
W2 = \frac{-16-\sqrt{16}}{-2} =  \frac{-20}{-2} = 10\\

L1 = 10\\
L2 = 6\\


so

{L,W} = {6,10} or {10,6}

but L > W  so

L = 10
W = 6

Find the length of YZ
emmainna [20.7K]
Larger triangle’s base length

a^2 + b^2 = c^2
a^2 + 3^2 = 8^2
a^2 = 8^2 - (3^2)
sqrt(a^2) = sqrt(55)
a = sqrt(55)
__________________

Smaller triangle’s base length:

The same formula applies.
a^2 + 3^2 = 5^2
a^2 = 5^2 - (3^2)
sqrt(a^2) = sqrt(16)
a = 4
____________

The finale!

Add the two side lengths of a, which is sqrt(55) + 4 (exact answer)
or... 11.416 (unrounded to thousandths place)

Good luck to you!
