Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.

Step-by-step explanation:
Answer: 14 dimes and 26 nickels
Explanation:
Dime = 0.10$
Nickel = 0.05$
Assume that all the coins were dimes
40 x 0.10$ = 4$
4$ - 2.7$ = 1.3$
1.3$/0.05$ = 26
Thus, 26 coins are nickels.
40 - 26 = 14
And 14 coins are dime.
Let’s check:
14(0.10) + 26(0.05) = 2.7$
1.4$ + 1.3$ = 2.7$
2.7$ = 2.7$
