1: 4 if the wew 35 surfboards at the beach how many were short boards?

7 of one type and 28 of the other

Step-by-step explanation:

Because you may have not specified enough information, I will give the numbers in the ratios. To start, weknow that one is x and one is 4x. Add these up to get 5x, and since there are 35 total, x = 7 and there are 7 of one type and 28 of the other.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

++x%5e2+=+1296%2f2+=+648+
