Question

Find the Surface area

Answer 1

Answer:

27m²

Step-by-step explanation:

surface area is area of all sides

these is two triangles and a rectangle

area of triangle = (base x height) /2 = (3 x 4)/2= 12/2 =6

area of rectangle = length x breadth = 5x3 = 15

surface area = area of triangle + area of triangle + area of rectangle

6 + 6 + 15 = 27m²
