Answer:
It's B
Step-by-step explanation:
Because I randomly guessed and that was the answer.
If you mean for the last one:
Triangle area=1/2bh
=1/2(4)(3x-5y)
Area of rectangle=l•w
=8(6x-y)
So combing them you get:
[(1/2)(4)(3x-5)]+[8(6x-y)]
Simplify: [8(3x+5)]+48x-8y
=24x+40+48x-8y
=72x-8y+40
You'd have to be given x and y to find a true value

Answer:
100 in²
Step-by-step explanation:
Since the figures are similar
the linear ratio of sides = a : b , then
ratio of areas = a² : b²
ratio of sides = 15 : 21 = 5 : 7
ratio of areas = 5² : 7² = 25 : 49
let the area of the smaller figure be x then by proportion
=
( cross- multiply )
49x = 4900 ( divide both sides by 49 )
x = 100
Area of smaller figure is 100 in²
