A triangle with sides measuring 300, 400 and 700 because 300+400+700=1400 which is higher than the first triangle 300+400+500=1200
To find the surface area of the figure , we need to add the surface area of all the faces
So the surface area of figure = Area of two lateral rectangular faces + Area of two triangular faces + area of base
hence
Surface Area of figure = 2(10*15) + 2( 1/2 * 8 * 12) + (12*15)
= 300 + 96 + 180
= 576 square feet
So correct option is the last one
Answer:
y-2=1/3(x+6)
Step-by-step explanation:
y-2=1/3(x-(-6))
y-2=1/3(x+6)
