I NEED HELP WITH GEOMETRY

Answer:
a) 136 square units
b) 92 square units
Step-by-step explanation:
A)
The triangle is worth:
16 * 16 / 2 = 128 + 16 * 16 / 2 = 128 = 256.
There is a rectangle in the middle with deletes 120 square units from 256.
256 - 120 = 136, so the first shape equals 136 square units.
B)
The smaller shaded triangles is 32 square units because 8 * 8 / 2 = 32.
The biggest one would be 15 * 8 / 2 = 60 square units.
32 + 60 = 92 square units.
Hope this helped!
Answer:
a. 136 [tex]units^{2}[/tex]
b. 92 [tex]units^{2}[/tex]
Step-by-step explanation:
a. Find the area of the triangle and the area of the rectangle, then subtract the area of the rectangle by the triangle.
Area of triangle: bxh / 2 = 32x16 / 2
= 512 / 2
= 256
Area of rectangle: bxh = 20 x 6
= 120
Total area: 256 - 120 = 136 [tex]units^{2}[/tex]
b. Just like a., find the area of the white triangle and the rectangle, then subtract the area of the triangle by the rectangle.
Area of triangle: bxh / 2 = 23x8 / 2
= 184 / 2
= 92
Area of rectangle: bxh = 23 x 8
= 184
Total area: 184 - 92 = 92 [tex]units^{2}[/tex]
