The perimeter of an equilateral triangle is 4 centimeters more than the perimeter of a square and the length of a side of the triangle is 8 centimeters more than the length of a side of the square. find the length of a side of the equilateral triangle. (an equilateral triangle has three sides of the same length.)

length of side = 36 cm

let x be the side of the square then x + 8 is the side of the triangle

perimeter of square = 4x and

perimeter of triangle = 3( x + 8 ) + 4 = 3x + 24 + 4 = 3x + 28

equating the perimeters

4x = 3x + 28 ( subtract 3x from both sides )

x = 28

length of side of triangle = x + 8 = 28 + 8 = 36 cm

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
