Answer:
Each area added together
Step-by-step explanation:
so depending on the type of prism you are going to use the formula for area to get the area of each side/face of the prism then simple add all the areas together
Just took the test and got the the correct answer *\(♡°▽°♡)/*
Look at the image down below!!
Answer:
Step-by-step explanation:
The measure of the floor of the rectangular room that is 12 feet by 15 feet. The formula for determining the area of a rectangle is expressed as
Area = length × width
Area of the rectangular room would be
12 × 15 = 180 feet²
The tiles are square with side lengths 1 1/3 feet. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet
Area if each tile is
4/3 × 4/3 = 16/9 ft²
The number of tiles needed to cover the entire floor is
180/(16/9) = 180 × 9/16
= 101.25
102 tiles would be needed because the tiles must be whole numbers.
That line means the other side is also x
remember pythagoran theorem
for legs length a and b and hypootnuse length c
a²+b²=c²
so
legs aer x and x
hyptonuse is 6
x²+x²=6²
2x²=36
divide both sides by 2
x²=18
sqrt both sides
x=(√9)(√2)
x=3√2
