Step-by-step explanation:
Answer:
BC ≈ 8.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle , that is
BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )
BC = 
≈ 8.6 ( to 1 dec. place )
Trapezoid since the sides are the same but the top and bottom are not
Answer:
197
Step-by-step explanation:
You have 6 sides of this object. So we will calculate six surface areas.
P1=5x5=25 ( on the top)
P2=9x5=45 ( on the bottom)
P3= 5x5= 25 (left side)
P4=6,4x5=32 (rightside)
P5= (9+5)x5/2=70/2=35 ( front trapeze)
P6=P5=35 ( behided trapeze)
P= p1+p2+p3+p4+p5+p6=
25+45+25+32+35+35 =197
