Answer:
Step-by-step explanation:
we know that
The area of the figure is equal to the area of a triangle plus the area of a parallelogram
<em>Find the area of triangle KLM</em>
we have
--> difference of the x-coordinates points M and K
--> difference of the y-coordinates points L and K
substitute
<em>Find the area of parallelogram JKMN</em>
--> difference of the x-coordinates points N and J
--> difference of the y-coordinates points K and J
substitute
The area of the figure is equal to
Answer:
44 %
Step-by-step explanation:
22 divided by 50 is 0.44 which is 44 percent
Answer:
b
Step-by-step explanation:
y = 1y
1y+0.4y =1.4y
( 30 / 100 ) * (15.40 ) = ( 3 / 10 )* (15.40) = 36.20 / 10 = 3.62$.
Answer:
382 cm²
Step-by-step explanation:
Front face + Back face:
A = 2(a + b)h/2
A = 2(14 cm + 8 cm)(7 cm)/2
A = 154 cm²
Left face:
A = 7 cm × 6 cm = 42 cm²
Right face:
A = 9 cm × 6 cm = 54 cm²
Bottom face:
A = 14 cm × 6 cm = 84 cm²
Top face:
A = 6 cm × 8 cm = 48 cm²
Total surface area =
= (154 + 42 + 54 + 84 + 40) cm²
= 382 cm²
