Question

Area between two shapes. Geometry IXL pls help !

Answer 1

Explanation:

The given figure is a right angle triangle. The formula for determining the area of a triangle is expressed as

Area = 1/2 × base × height

Considering the outer triangle,

Base = 33km

Height = 40km

Area = 1/2 × 33 × 40 = 660km²

Considering the inner triangle,

Base = 19km

Height = 23km

Area = 1/2 × 19 × 23 = 218.5km²

The area of the shaded region = Area of outer triangle - area of inner triangle. It becomes

660 - 218.5 = 441.5 km²

Answer 2

The answer to your question is A = 441.50 km²

Explanation:

Data

Big triangle Small triangle

base = 33 km base = 19 km

height = 40 km height = 23 km

Process

1.- Calculate the area of the big triangle

Area = base x height / 2

Substitution

Area = 33 x 40 / 2

= 1320 / 2

= 660 km²

2.- Calculate the area of the small triangle

Area = 19 x 23 / 2

= 437 / 2

= 218.5 km²

3.- Subtract the small area to the big area

Share area = 660 - 218.5

= 441.50 km²
