Answer:
D)
DF = 52
AB = 48
Step-by-step explanation:
Use the two lengths of sides already given.
Divide to find the scale factor:
20 / 5 = 4
Scale factor: 4
Now multiply to find the unknown sides:
13 × 4 = 52
12 × 4 = 48
DF = 52
AB = 48

Answer:
45 cm^2
Step-by-step explanation:
The area of a triangle can be found using:
a= (b*h)/2
We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.
a=(18*5)/2
Multiply 18 and 5 first
a=90/2
Divide 90 by 2
a=45
So, the area is 45 cm^2
