Answer:
length=25 width=17
Step-by-step explanation:
l+w=42
start by guessing a pair of numbers that equals 42 i chose 22+20
since these two numbers are 2 digits apart,
5-2=3
now we have to add 3 to 22 and subtract 3 from 20
now it is 25+17 which still equals 42
Answer: 36.2
We have 4 x ( 3 / 2 ) = 12 / 2 = 6;
x= 10 In (17)
