the side length of a square measures 2 x+1 and the side lengths of a triangle are 2x, 2x, and 3x+10.The square and triangle have the same perimeter. Find the perimeter

perimeter = 52

Step-by-step explanation:

side of square = 2x + 1

p = 4 × s (side)

p = 4(2x +1) from the given

p = 8x + 4 we will come back for this equation

side of trianles = 2x,2x,3x + 10

p = s + s + s ( all the three sides)

p = 2x + 2x + 3x + 10

p = 7x + 10we got another equation we will use it later

8x + 4 = 7x + 10

8x - 7x = 10 - 4

x = 6 ... now lets substitute x

8x + 4

8 × 6 +4

48 + 4

52

the same thing will happen if we substitute for the perimeter of triangle too.

hope u like it ‍❤️‍❤️‍‍❤️‍

for any question comment me

x = 12

y = 15
