Answer:
QT = 16
Step-by-step explanation:
ΔQRS ~ ΔQRT
In similar triangles, corresponding angles are in same ratio.

Cross multiply,
QT * 25 = 20 * 20

60% of 90 is 54...............
Answer:
Length: 48
Width: 12
Step-by-step explanation:
Substition
l - 2w = 24
I = 60 - w
60 - w - 2w = 24
60 - 3w = 24
-3w = -36
w = 12
Substitute it into the equation to get the length.
l = 60 - 12
l = 48
