Answer:
A. 312 cm²
Step-by-step explanation:
The figure compromises of a rectangle and 2 equal triangles.
Area of the figure = area of the rectangle + area of the two triangles
Area = L*W + 2(½*b*h)
Where,
L = 16 cm
W = 12 cm
b = 12 cm
h = 10 cm
Plug in the values
Area = 16*12 + 2(½*12*10)
= 192 + 120
= 312 cm²
The formula for the area of a triangle is 1/2*b*h=a.
1/2*b*14=56
b*14=112
b=8
45 / 9 = 5
55 / 5 = 11

Answer:
x = 19
Step-by-step explanation:
The two angles with measures are supplementary.
6x + 9 + 4x - 19 = 180
10x - 10 = 180
10x = 190
x = 19
