Answer: the missing measure on the big rectangle is 30 feet.
Step-by-step explanation:
If the small rectangle was enlarged to create the big rectangle, it means that they are similar. This also means that the dimensions of the larger rectangle different form the dimensions of the smaller rectangle by a constant ratio or factor.
The smaller rectangle has a length of 12 feet and width of 2 feet. The larger rectangle has a length of x feet and width of 5 feet. This means that
x/12 = 5/2
Cross multiplying, it becomes
2x = 12 × 5 = 60
x = 60/2 = 30
I think is you just need to multiply that input number just to get the right answers
Example: 5 multiply by 5 equal 25
Try it
Answer:
117
Step-by-step explanation:
4 : 9 = 52 : 117
Since
4 : 9 = 52 : X
Then we know
9/4 = X/52
Multiplying both sides by 52 cancels on the right
52 × (9/4) = (X/52) × 52
52 × (9/4) = X
Then solving for X
X = 52 × (9/4)
X = 117
Therefore
4 : 9 = 52 : 117
