Answer:
13.5
Step-by-step explanation:
7 1/2=7.5
7.5/5*9=13.5
Answer:
9.562
Step-by-step explanation:
Use the Heron’s Formula to find the area of a triangle when all three sides are known (SSS). In the formulas below, S represents the semi-perimeter of the triangle, and ABC are the three given sides.
You must first know the semi-perimeter (S) before you are able to calculate the area.
S= 1/2 (A+B+C)
Area = √S(S-A)(S-B)(S-C)
In your case:
<u>semi perimeter </u>
= 1/2 (9+4+6)
= 19/2
= 9.5
<u>Area </u>
= √9.5(9.5−9)(9.5−4)(9.5−6)
= √91.4375
= 9.562
Answer:
2/3
Step-by-step explanation:
Cancel the common factor 2 = 2/3
<u><em>Answer:</em></u>
79.8 (Guessing)
<u><em>Step-by-step explanation:</em></u>
for the side walls, split 19 in half, and get 9.5.
9.5 + 9.5 = 19
19 + 19 + 29.2 + 12.6
(2 walls) + (bottom floor) + (height/y)
79.8
<h2>The above state tells only about the sum of their angle not about their areas. You are right there sum of angles is same but their areas are different. Let's take another example, rectangle also have sum of angles equal to 90 ° but it's not that rectangle is equal to circle. Square and Rectangle are equal because their areas are same.</h2>
