Hi,

$\sqrt{163} = 12.76$

The actual square root value is ≈12.767145334803704

But we have taken only significant figures and it is as 12.76.

A rectangle has a perimeter of 196 meters and a length of 50 meters.What is the width of the rectangle? Explain.

matrenka [14]

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
