Question 893340
x = width
2x = length  {it is twice as long as it is wide}


Area of a rectangle = width x length

x(2x) = 32 {substituted width and length into area formula}
2x² = 32 {multiplied}
x² = 16 {divided each side by 2}
x = 4 {took square root of each side}
2x = 8 {substituted 4, in for x, into 2x}


width = 4 cm
length = 8 cm


Perimeter of a rectangle = 2(width) + 2(length)
= 2(4) + 2(8) {substituted 4 for width and 8 for length}
= 8 + 16 {multiplied}
= 24 {added}


Perimeter = 24 cm
