What is the area of the figure below ?
Airida [17]

Answer:

Step-by-step explanation:

Area of the figure = area of the down triangle + area of trapezium + area of the upper triangle

Down triangle:

Base b = 8 in

Height = 6 in

Area = \frac{1}{2}bh\\=\frac{1}{2}*8*6\\\\=4*6

= 24 in²

Trapezium:

bases a = 4 in & b = 6 in

Height h =  5 in

Area=\frac{(a+b)h}{2}\\\\=\frac{(4+6)*5}{2}\\\\=\frac{10*5}{2}\\\\=5*5

= 25 in²

Area of the upper triangle:

Base b = 6 in

Height = (8 - 5) = 3 in

Area=\frac{1}{2}bh\\\\=\frac{1}{2}*6*3\\\\=3*3

= 9 in²

Area of the figure = 24 + 25 + 9 = 58 in²

3x + 2y = 32<br> how to solve
lord [1]
Answer: y= 16 - 3/2x

Step-by-step explanation:
3x+2y=32 (subtract 3x from both sides)
2y=32-3x (divide both sides by 2)
y= 16 - 3/2 x

If solving for x:
3x + 2y = 32
3x = 32- 2y
x = 32/3 - 2/3 y
