I have a few minutes to turn it in

The side of the square is 15m

The side of the triangle is 20m

Step-by-step explanation:

P square = 4s  where s is the side length

P triangle = 3 x where x is the side length

x = s+5

The perimeters are equal

4s = 3x

Replace x with s+5

4s = 3(s+5)

Distribute

4s = 3s+15

Subtract 3s from each side

4s-3s = 15

s = 15

The side of the square is 15

x =s+5

  =15+5

   = 20

The side of the triangle is 20

Step-by-step explanation:

The perimeter of a square is , where s is the side length.

The perimeter of an equilateral triangle is , where a is the side length.

The side length of the equilateral triangle is 5 more than the side length of the square.

The perimeter of the square and equilateral triangle are equal.

Expanding brackets.

Subtracting 3s from both sides.

The side length of the square is 15 meters.

The side length of the triangle is 20 meters.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
