The area of the triangle is 27cm.
Answer:
5 * .487 = 2.435
Step-by-step explanation:
5 * 487 = 2435
There are 3 digits after the decimal in the original problem, so there will be 3 digits after the decimal in the answer
5 * .487 = 2.435
x = 0.17(repeating 7) (1st)
10x = 1.77 (2nd)
subtract (1st) from (2n)
9x = 1.77 - 0.17
9x = 1.6
90x = 16
x = 16/90
x = 8/45
answer
8/45
