26.5 square centimeters

Step-by-step explanation:

You are given two triangle combined and asked to find the area of the figure. The equation to find the area of a triangle is

Area = 1/2 * base * height

where

Triangle 1 has a base=10 cm and a height=3.5 cm

Triangle 2 has a base=6 cm and a height=3 cm

To find the area of triangle 1,

Area = 1/2 * 10 * 3.5 = 17.5 square centimeters

To find the area of triangle 2,

Area = 1/2 * 6 * 3 = 9 square centimeters

So, by adding these two areas we will get the total area of the figure.

Total Area = 17.5 + 9 = 26.5 Square Centimeters

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
