Answer:
73/30 or2.43
Step-by-step explanation:
The answer is 73/30
Answer: 5.04
= 9.87
9.87 divided by 1.96 = 5.04
The area=base×height
=10×4
=40cm^2
perimeter=2(length+breadth)
I think to find the height Dc you use the pythagoras theorem of
Dc^2=de^2+ce^2
=√16+9
=5
therefore the perimeter will be
p=2(5+10)
=20cm
I hope this helps and sorry if it's wrong
