Answer 1

Area of triangle is base x height over 2
20 x 7 = 140
140/2 = 70
area of each triangle is 70m2
add the areas together to get the total area
70 + 70 = 140
total area is 140m2

Answer 2

Answer:

20 m²

21 m²

less than

Step-by-step explanation:

Trapezoid

The trapezoid has been broken into two triangles and a rectangle. The two triangles both have the same dimensions, so both have the area ...

 A = (1/2)bh = (1/2)(2 m)(5 m) = 5 m²

The rectangle has area ...

 A = bh = (2 m)(5 m) = 10 m²

So, the total area of the trapezoid is ...

 trapezoid area = 5 m² +10 m² +5 m²

 trapezoid area = 20 m²

__

Kite

The kite has been broken into two triangles, so the area of each of them is ...

 A = (1/2)bh

 A = (1/2)(7 m)(3 m) = (21/2) m²

Then the area of the two halves of the kite will be ...

 kite area = 2 × (21/2 m²)

 kite area = 21 m²

__

The area of the trapezoid is 1 m² less than the area of the kite.
