Answer:
Option 4
Step-by-step explanation:
Area of a trapezoid =
Here,
and
are the bases and 'h' is the height between the bases.
Area of the composite figure = Area of two trapezoids given

Option 4 is the answer.
Answer:
$3.49 * 3 = $10.47
Step-by-step explanation:
Answer:
y=x
Step-by-step explanation:
7 x 13 = 91 x 4 = 364 = Area of the four rectangles.
8 x 7 = 56 x 2 = 112 = Area of the two squares.
364 + 112 = 476 cm2
Surface Area = 476 cm2

V=B+15
V+2B=180
Therefore:
3B+15=180
B=55
V=70
Check:
V+2B=180
70+2(55)=180
70+110=180
180=180. Checks.
