Answer:
1)2(lb+bh+hl)
=2(17*12+12*8+8*17)
=2(204+96+136)
=2*436
=872 in^2
2)2*pi*r(r+h)
=2*3.14*14(14+29)
=6.28*14(43)
=6.28*14*43
=3780.56 mm^2
3)A=11*4.3+3*6 +3*8+11*3(Area of each plane figure -triangle and rectangle)
=47.3+18+24+33
=122.3cm^3
4)h*(sum of II sides)+14*8+19*8+14*8+25(Area of plane surface-trapezium,rectangle,square)
=12.1(19+5)+112+152+112+25
=12.1*24+401
=290.4+401
=691.4ft^2
Answer:
Step-by-step explanation:
The sequence is arithmetic because the terms have a common difference.

The required polygon whose area is to be calculated is attached below :
Answer:
16 unit²
Step-by-step explanation:
From the graph, the polygon is a triangle with height of 8 units and base of 4 units ;
Area of a triangle is given as :
Area = 1/2 * base * height
Area = 1/2 * 4 * 8
Area = 2 * 8
Area = 16 unit²
12(20-17) - 3*6
12 (3) - 18
12*3 - 18
36 - 18
18
Answer:
A, or 50.24 ft.
Step-by-step explanation:
Doing the equation above, we know the radius of the circle, which is 8 ft.
8ft times 2 is 16ft.
16ft times pi gives us (rounded) 50.24 ft.
