Answer:

You need to draw the diagram to understand the problem easily. Teh diagram will show the right triangle, acute angle with the base 7º, height is 663 m, and "x" is the base of the triangle.

using the tangent ratio:

tanΘ = opposite / adjacent

tan7º = 663 m / x

x = 663 m / tan7º
x = 5,399.7 m

change m to km. 1,000 m = 1km

5,399.7m * 1km/1,000 m = 5,399.7 km/1000 = 5.3997 km or 5.4 km

B. 5.4 km

Answer:

$\huge\boxed{\sf 18 cm\²}$

Step-by-step explanation:

The figure consists of 2 rectangles.

Rectangle 1 Area:

Length = 5 cm

Width = 2 cm

Area = Length * Width

A = 5 * 2

A = 10 cm²

Rectangle 2 Area:

Length = 4 cm

Width = 2 cm

Area = 2 * 4

A = 8 cm²

Area of the whole figure:

= Rectangle 1 + Rectangle 2

= 10 + 8

= 18 cm²

$\rule[225]{225}{2}$

Hope this helped!
