Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A = 
ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
So a square pyramid is like the pyramids in egypt so
surface area of pyhraid=base+4 triangles
surface area=144
baswe=36
subsitute
144=36+4 times triangles
subtract 36 from both sides
108=4 triggles
divide by 4
27=trignels
the area of 1 triangle is 27 ft^2
