Answer:

Length = 7.83, Width = 3.83

Explanation:

Assign variables. Let x represent the width

Area (L x W) = 30 m²

(4 + x)(x) = 30

4x + x² = 30

x² + 4x - 30 = 0

Apply Quadratic Formula


(-4 + √(4^2 - 4(1)(-30)))/((2)(1))

Solve

x = -2 ± √34

x = 3. 83... or x = -7.83 (reject this one)

Width = 3.83

Length = x + 4 = 7.83
