The triangle below has a total perimeter of 450 cm.

picture of a triangle with sides 128 and 150. Third side unknown

Write an equation and solve it to find the length of the longer side of the rectangle.

128x + 150 = 450; x = 2.34 cm

x + 278 = 450; x = 172 cm

2x + 278 = 450; x = 86 cm

150x + 128 = 450; x = 2.15 cm

which is answer

Answer 7

So you have 2 sides of a triangle known whose perimeter is 450 and you want to know the length of the third side?

128 + 150 + x = 450

278 + x = 450

x = 450 - 278

x = 172. Makes a heck of a lot more sense to me than 2.15

Answer 8

yea :) which one is it?
