- Formula For Area Of Trapezoid:

-----------------------------------------
A = 10
B = 18
H = 6
- Plug Numbers Into Equation:

10 + 18 = 28
28 ÷ 2 = 14
14 · 6 = 84
84

Answer:
279638.5416666667
Step-by-step explanation:
Angle E=130degrees because those two are congruent. Therefore if you 180-130 you'll get the other angle in the triangle with 70degrees and y. 180-130=50degrees. Then add 50 and 70. 50+70=120degrees. A triangle is supposed to have 180 degrees inside.
180-120=60degrees.
Therefore y=60degrees
Answer:
144.2 cm
Step-by-step explanation:
Length of the iron rod is 7.4cm
Radius is 3.1m
Therefore the surface area can be calculated as follows
= 2πrl
= 2×3.142×3.1×7.4
= 144.2 I'm
Hence the surface area is 144.2cm
Let books =x and games =y
2x+2y=26
4x+1y=28
If you solve for x and y, x=5 and y=8
