Question

The pictures are the questions

Answer 1

A) Photo attached

B) 260

Explanation:

A) Image Attached

B) LSA = 2bs where, b = base, s = slant height

LSA = 2*10*13

= 260

OR

LSA = sum of area of the 4 triangles

= 4 * area of the triangle

= 4 * (base * height/2)

= 4 * (10*13/2)

= 4*(5*13)

= 4*65

= 260

Answer 2

Check the picture below.

so the lateral area is really just the area of the green triangles.

`\stackrel{ \textit{area of the four triangles} }{4\left[\cfrac{1}{2}(\underset{b}{10})(\underset{h}{13}) \right]}\implies \text{\LARGE 260}~in^2`
