Sagot :
Answer:
12cm and 17cm
Step-by-step explanation:
"the length of one side is 11cm more than half the length of another"
WHICH MEANS
x and 11 + x/2
solving
2(x) + 2(11 + x/2) = 58
2x + 22 + x = 58
3x = 58 - 22
3x = 36
x = 12
now substitute x = 12
x and 11 + x/2
12 and 11 + 12/2
12 and 11 + 6
12 and 17
12cm and 17cm
