Answer:
Step-by-step explanation:
Area = side*side
side * side = 49
side * side = 7*7
side = 7 inches
Perimeter = 4*side
=4 * 7
= 28 inches
Answer:
C 288
Step-by-step explanation:
using counter clockwise rotation
360/5 x 4 =288
Answer:
50
Step-by-step explanation:
Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:
Fraction: 9 / 10 it's already reduced to lowest terms
Fraction: 11 / 12 it's already reduced to lowest terms
Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:
Denominator 10, factored = 2 * 5
Denominator 12, factored = 22 * 3
LCM (10, 12) = 22 * 3 * 5 = 60
Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):
For fraction: 9 / 10 is 60 : 10 = (22 * 3 * 5) : 10 = 6
For fraction: 11 / 12 is 60 : 12 = (22 * 3 * 5) : 12 = 5
Step 4: Expand fractions to bring them to the common denominator (LCM):
9 / 10 = (6 * 9) / (6 * 10) = 54 / 60
11 / 12 = (5 * 11) / (5 * 12) = 55 / 60
