Since it’s a square room, each side has length of 300ft. Simply use the Pythagorean Theorom to find the length from one corner to the opposing corner.
300^2 + 300^2 = c^2
90000 + 90000 = c^2
180000=c^2
Find the square root of 180000
C= 424.264069
The length from opposing corners is roughly 424.26ft
Area if the rectangle = 42 sq. inch
Area of a rectangle = l × b
42 = 12 × b
b = 42/12 = 3.5 inch
Now, perimeter of a rectangle= 2(l + b)
= 2(12+3.5) = 2(15.5) = 31 inches
Answer:
True, True, False, True
Step-by-step explanation:
The scale factor was D. 4. We can figure this out by multiplying 3 by 4 to get 12 and 1 by 4 which is 4 to get the dimensions of the larger triangle.
I hope this helped! :-)
