Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
angle A = 30
(2x-9) = (2x+21)
+9 +9
2x=2x+30
-2x -2x
=30
Perimeter = (2)(length) + (2)(height)
Let's call the width x and the length y
Therefore perimeter = (2x)(2) + (5y)(2)= 4x+10y
2x÷(4x+10y) is the answer :)
