Question

math helppp find the area of each figure. When necessary, use familiar figures.(see chart in comments)
38.5 m2
108 m2
105 m2
54 m2

Answer 1

What shape and size is the figure?

Answer 2

area of ttriangle is 1/2* B * H

Answer 3

im assuming you only want the area of the yellow shaded portion

Answer 4

First, must find the area of the larger triangle
we use the pyth theorem to find the full base of that larger one = 15

A larger = 1/2 * b *h = 1/2 *15 * 9 = 67.5

area of smaller dotted in triangle
= 1/2 * b * h = 1/2 * 3 * 9 = 13.5

Note: if entire base is 15 - yellow trianlge is 12 then sm dotted triange base is 3

now subtract 67.5 - 13.5 = 54.0

that is the area of the yellow shaded triangle
