Answer:
21.25
Step-by-step explanation:
diagonal is 21.25
the area is 216.75
the perimeter is 59.5
500 = 10x + 2 * 15 * 5 + 15x
500 = 25x + 150
500 - 150 = 25x
350 = 25x
x = 14
Triangular ends: 14 * 10 = 140
Base rectangle: 14 * 15 = 210
side rectangles: 5 * 15 * 2 = 150
140 + 210 + 150 =
Answer:
The net cost of the photocopier before january 1 is <u>$1350.</u>
