Question

Geometry: The rectangle shown has a perimeter of 34cm and the given area. Its length is 5 more than twice it's width. Write and solve a system of equations to find the dimension of the rectangle

Answer 1

w - width

2w + 5 - length

w + w + (2w + 5) + (2w + 5) = 6w + 10 - perimeter

34 cm - perimeter

The equation:

6w + 10 = 34 subtract 10 from both sides

6w = 24 divide both sides by 6

w = 4 cm

2w + 5 = 2(4) + 5 = 8 + 5 = 13 cm

Answer: Width = 4cm, Length = 13cm
