A poster is 3 inches long. it is 4 times as wide as it is long find the perimeter and area of the poster?

1 answer:

8 0

So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches

In a choir, the ratio of boys to girls is 5 to 6. There are 10 boys in the choir.

Lina20 [59]

Answer:

Answer:

5:6 --> 10:12

Step-by-step explanation:

A good way to think of this is to provide a perspective: there are 5 boys every time there is 6 girls. So if there is 10 boys, that means there would be 12 girls (because 5 *2 = 10 and 6*2 = 12).

tl:dr: 5 *2 = 10 so 6*2 = 12
