Area = 1/2 * Base * (vertical) height = 1/2 * 16 * 9 sq km = 72 sq km

A circle with a radius of 0.9 km has an area of 2.54 square km

22.1 km. Area of a rectangle =L x W

Its height is 4 km because 2(4)+2(7) = 22 km which is the perimeter

"1 km" is a distance. It has no area.1 square km = 10,763,910 square feet (rounded)

Area of the triangle (1/2 x base x height) =1/2 x 2 km x 3 km = 3 km2

168 km². Area of rectangle = Length*Breadth = 13*7 = 91 km² Area of triangle = 1/2*Base*Height = 1/2*14*11 = 77 km² Area of figure = Area of rectangle + Area of triangle = 91+77 = 168 km²

168 km². Area of rectangle = Length*Breadth = 13*7 = 91 km² Area of triangle = 1/2*Base*Height = 1/2*14*11 = 77 km² Area of figure = Area of rectangle + Area of triangle = 91+77 = 168 km²

Area = 1/2 * Base * (vertical) height = 1/2 * 16 * 9 sq km = 72 sq km

The area of a rectangle is length times width, so 7 km times 13 km is 91 square km. Now the area of a triangle is 1/2 base times height. We'll take 14 times 11 and get 154. Divide this now by 2 to get that the area of our triangle is 77 square km. Now we just need to add 91 and 77 to get an answer of 168 square km.
