Question

What is the area of the shaded region in the figure above? Please help i don't understand triangles. Also can you explain how to solve this.

Answer 1

the area of the shaded region is 119.5

Explanation:

area of a triangle formula 1/2bh (b= base) (h=height)

area of big triangle work

1/(20)(18)

20x18= 360

360 divided by 2 is 180 area of big triangle is 180

moving on to smaller triangle

1/2bh

1/2(11)(11)

121/2

60.5

THEN you subtract using bigger triangle by smaller

180-60.5=119.5
