Answer:
158.76
Step-by-step explanation:
11.7*15.6=182.52
182.52/2=91.26
Area of BCD=91.26
7.5*18=135
135/2=67.5
Area of BAD=67.5
Altogether:
91.26+67.5=158.76
Answer:
B
Step-by-step explanation:
Answer:
5.20 to the nearest hundredth.
Step-by-step explanation:
The altitude line bisects the base of the triangle to form 2 right angled triangles with hypotenuse = 6 and the base = 3.
So, by the Pythagoras theorem the altitude is calculated as follows:
6^2 = 3^2 + x^2
x^2 = 36 - 9 = 27
x = √27
= 5.20 to the nearest hundredth.
