In a rectangle, opposite sides are equal so you can multiply the side lengths by 2 and add them so 16(2)+34(2) and yu get 32+68. The perimeter is 100
Answer:
Decimal expansion of 1/5 = 0.2
2 + 2 equals to 4
You can do it on the calculator too.
A=LW, we are told that the dimensions are 42 and 48 so:
A=42*48
A=2016in^2
Answer:

Step-by-step explanation:
We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:

In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:




Since the area of a square is the side length square then...

The square root and the squared cancel out giving us...
