Answer:
x=16;y=8
Step-by-step explanation:
x=length
y=width
the length of a rectangle is twice the width
so,
x=2y........(1)
the perimeter is 48 inches
so,
2(x+y)=48
x+y=24....(2)
2y+y=24 [from 1]
y=8........(2)
so
x=2.8 [from 1 &2]
x=16

Step-by-step explanation:
315 divide by 9= 36
2*36=72
7*36= 252
72:252
We know that
in the triangle TQS
<span>applying the Pythagorean theorem
QS</span>²=TS²+TQ²---------> TQ²=QS²-TS²--------> TQ²=18²-9x²-----> equation 1
in the triangle TRS
TS²=TR²+RS²--------------> TR²=TS²-RS²-------> TR²=9x²-144----> equation 2
in the triangle QTR
TQ²=TR²+36-----------> equation 3
<span>I substitute 1 and 2 in 3
</span>18²-9x²=9x²-144+36--------> 18x²-432=0------> x²=24-------> x=√24
x=2√6
TS=3*x------> 3*2√6-----> 6√6
TS=6√6 units
the answer is
TS=6√6 units
<span>6 is the square root of 6 units</span>
