Answer:
[See Below]
Explanation:
✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:
✧ Square ∼ s² (Side Squared)
✧ Triangle ∼ ½ × b × h
✦ So now just solve for each area:
✧ Square ∼ 15² = 225
✧ Triangle ∼ ½ × 15 × 3 = 22.5
✦ Now add each area together to get the total area:
✧ 225 + 22.5 = 247.5
