Answer

Substitute \(b\) with \(h + 3\) and solve for \(A\): \(A = \frac{1}{2}(h + 3)h\).

Steps

Step 1 ：Let height be \(h\), then base is \(b = h + 3\).

Step 2 ：The area of a triangle is \(A = \frac{1}{2}bh\).

Step 3 ：Substitute \(b\) with \(h + 3\) and solve for \(A\): \(A = \frac{1}{2}(h + 3)h\).
