5*5=25
Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards
The total area is 448 in^2. Each triangle is 56 in^2 and each parallelogram is 140 in^2
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2 where a and b are the sides and c is the hypotenuse
21^2 + 28^2 = c^2
441 + 784 = c^2
1125 = c^2
Now you need to take the square root of 1125 to find the value of x, which would be approx 33.5
