Answer:
245.76
Step-by-step explanation:
The mistake is line 4, she should have divided 42 by 5, not add 5 and 16
3x4x1/2= 6inches Multiply the base by the height and after multiply by one half
The average is (0.76+0.88) / 2 = 1.64 / 2 = 0.82
Answer: 48 meters
we already know that one side is 50 m, so since it's a
rectangle you can multiply 50 by 2 which gives you 100. Know you have two sides left (which would be the same number) . You can do it easy and subtract 196 and 100 which gives you 96. Then, divide 96 by 2 and you get 48.
---- check: do 48(2)+50(2) it will give you 196
