Answer:

172cm^2

Explanation:

Surface Area of Triangles;

A=B x H / 2

=(4x3) /2

= 6cm

Multiply 6 by 2 since there are two triangles at both ends

6 x 2 =12cm^2

Surface area of the rectangles;

A=LW

=10x5

=50cm

Multiply by three since there are three triangles

50cm x 3 = 150cm^2

Add everything both total triangle and rectangle surface areas together

A= 12 + 150

=172cm^2
