Answer:
<h2>A = 145 cm</h2><h2 />
Step-by-step explanation:
total length = 445 cm (A + B + C)
A = 45 + B
B = C/2
find A
A + B + C = AC
(45 + B) + (C/2) + C = 445
45 + C/2 + C/2 + C = 445
2C = 445 - 45
C = 400/2
C = 200
B = 200/2
B = 100
A = 45 + 100
A = 145
proof:
445 = 145 + 100 + 200
445 = 445 ----OK
11^2 is the answer im pretty sure
Answer:
20 cm
Step-by-step explanation:
5n × 3n = 2×120
15n²=240
n²=240/15 =16
n=√16 = 4
base = 5× 4 = 20
