Area of rectangle = l*w
Area of triangle = (1/2)*l*w

Based on the figure:

Area of triangles = 2*(1/2)*l*w
= 2*(1/2)*24*14 = 336 cm^2

Area of side rectangles = 2*l*w
= 2*44*25 = 2200 cm^2

Area of bottom rectangle = l*w
= 44*14 = 616 cm^2

To find the total surface area, you would add all of the sides together:

336+2200+616= 3152 cm^2

Don’t be afraid to ask any questions, if you have any :D
