Answer:
577
Step-by-step explanation:
<em>l = 16 feet</em>
<em>w = 3 feet</em>
- Step-by-step explanation:
<em>A = l×w</em>
<em>l = 10+2w</em>
<em>48 = (10 + 2w)w</em>
<em>48 = 10w + 2w² | : 2</em>
<em>24 = 5w + w²</em>
<em>w² + 5w - 24 = 0</em>
<em>w² + 8w - 3w - 24 = 0</em>
<em>w(w + 8) - 3(w + 8) = 0</em>
<em>(w - 3)(w + 8) = 0</em>
<em>w - 3 = 0 => w = 3 feet</em>
<em>w + 8 = 0 => w = - 8 ∉ N </em>
<em>l = 10 + 2w</em>
<em>l = 10 + 6</em>
<em>l = 16 feet</em>
<em />
<em>A = l×w = 16ft×3ft = 48ft² </em>
45-15= 30
30/3= 10
