Question

The perimeter of a triangle is 29 feet where one side of the triangle is twice the length of the shortest side. The largest side is 13 feet more than the shortest side. How long is the shortest side? Select one: a. 4 feet b. 16 feet c. 8 feet d. 17 feet John is trying to fence his yard. The length of his yard is 112 feet and the width of his yard is 225 feet. Use the formula for perimeter to find out how much fencing John needs. The formula for the perimeter is P = 2w + 2l where P is the perimeter, w is the width, and l is the length. Select one: a. P = 674 feet b, P 25,200 feet c. P = 337 feet d. P = 450 feet

Explanation / Answer

Shortest =x

largest =x+13

another = 2x

Set up as

x+ (x+13) +2x =29

4x+13=29

4x=16

x=4

Thus, Shortest side is 4 feet

Correct option is A

===========

P= 2(112 +225)

=674 feet

Correct option is A
