You see, that it's divided into triangles. Find the area of each triangle using the formula: the area of triangle is base*height*1/2. Then, add all the areas altogether.
Answer:
Lateral surface area: 364 yd^2
Total surface area: 624 yd^2
Step-by-step explanation:
Lateral area: 2(14x13) = 364 yd^2
Total area= 364 + 120 + 140 = 624 yd^2
