Question

80 centimeters. measurements could be the length and width of the rectangle

Answer 1

Answer:

Let x=width

length = 2x+4 (This is 4 more than twice the width)

Perimeter = all 4 sides added together

80 = x + x + (2x+4)+ (2x+4)  Simplify by combining like terms

80 = 6x+8  Subtract 8 from both sides

80-8 = 6x+8-8  Simplify

72 = 6x  Divide both sides by 6

72/6 = 6x/6  Simplify

x=12 cm is the width

Solve for length

length = 2x+4 = 2(12)+4 = 28 cm is the length
