Gre4nikov [31]

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

The area of a parallelogram is simply its base (6.1 miles) multiplied by its height (2.6 miles).

Substitute the values into the formula for area.

A=6.1\cdot2.6

Multiply.

A=\boxed{15.86}

Note that the answer is given in square miles (\text{mi}^2) since both of the measurements used are in miles.
