Area and Perimeter Algebraic Expressions

The perimeter of a triangle is 65 ft. Side "a" is 7 ft shorter than side "b". Side "c" is twice as long as side "a". Find the length of each side.

• Side "a" = 75 ft

  Side "b" = 80 ft

  Side "c" = 37.5 ft

• Side "a" = 15 ft

  Side "b" = 20 ft

  Side "c" = 30 ft

• Side "a" = 35 ft

  Side "b" = 40 ft

  Side "c" = 70 ft

The length of a rectangle is 2 times the width. The perimeter is 126 cm. Find the length and width of the rectangle.

• Length = 21 cm

  Width = 21 cm

• Length = 86 cm

  Width = 43 cm

• Length = 42 cm

  Width = 21 cm

• Length = 126 cm

  Width = 63 cm
