Question

Help! Help me pleaseeee!! I will give brainiest!!! Pleasee!!

Answer 1

divide the shape into 2 triangles and 1 rectangle

left triangle :

hypotenuse = 7 in

height = 6 in

base = x

find the base using pythagoras theorem

x = √( 7² - 6² )

x = √13

x = 3.6 in

find it's area

6 × 3.6 ÷ 2 = 10.8

right triangle :

hypotenuse = 9 in

height = 6 in

base = x

find the base using pythagoras theorem

x = √( 9² - 6² )

x = √45

x = 6.7 in

find area

9 × 6.7 ÷ 2 = 30.15 in

middle rectangle :

16 in - left tri. base = base

16 - 3.6 = 12.4

find area

6 × 12.4 = 74.4

sum of the area

10.8 + 30.15 + 74.4 = 115.35
