Please help, nobody is helping I need to find surface area

Reil [10]

Answer:

A) 147.6 sq m

Step-by-step explanation:

Separate the pyramided out into 4 triangles and add those

3 of them (sides) will be the same

$A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20$

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.

The area of all 3 sides together is 40*3 = 120 sq m

For your base, your height will be 6.9 and your base is 4

A = 13.8 sq m

multiply by 2 again for the entire base

A=27.6 sq m

Now add both

120 + 27.6
