Answer:
18 inches and 9 inches
Step-by-step explanation:
Given, The base of a triangle is twice of the height.
Area = 81 sq inches
Let, Base (b) = 2x
Height (h) = x
Area of the triangle = \frac{1}{2}bh
\frac{1}{2}bh = 81
or, x^{2} = 8
Base = 2×9 inches = 18 inches
Height = 9 inches

Answer:
270m^3
Step-by-step explanation:
Area of the base times Hight. 9*5= 45 area of base 45*6= 270m
Algebraically, that will be expressed as:
