Answer:
Step-by-step explanation:
Base, b = 1/3
Height, h = 12feet = (12x 0.305)metres = 3.66m
Area of triangle= 1/2 bxh
A = 1/2 x 1/3 x 3.66
A = 0.61m^2
Or in feet's
Area of triangle = 1/2 bxh
A = 1/2 x 1/3 x 12 =2 feet^2
The answer to your question is 13<2/3
4x + 6 + 5x + 3 = 90
9x +9 = 90
( Subtract 9 from 9 and 90 )
9x = 81
( Divide 9x and 81 by 9 )
x = 9
Hope this helps.
