The length is 5 m longer than the width. Let width = W.<br><br>
[[model:questions/solutions/q7551.png]]<br><br>
&bull; Length = W + 5<br>
&bull; Perimeter = 2(W + W + 5) = 2(2W + 5) = 50<br>
&bull; 2W + 5 = 50 ÷ 2 = 25<br>
&bull; 2W = 20, so W = 10 m<br>
&bull; Length = 10 + 5 = 15 m<br>
&bull; Area = Length × Width = 15 × 10 = 150 m&sup2;<br>
<br>
Length = 15 m, Area = 150 m&sup2;.<br>
Check: Perimeter = 2(15 + 10) = 50 m. ✓
