First, calculate the area of the square, which is 25
next, find the area of one half of the triangle by multiplying 2.5 and 4 (10), then dividing that by 2 (5).
since the two half’s of the triangle are symmetrical, just add 5 and 5 to get 10.
add the area of the triangle (10) and the square (25) to get the total area.
the answer should be 35
hope this helps!
The area of the triangle is 14.1 square meters
<h3>How to determine the triangle area?</h3>
The side lengths are given as:
5m, 6m and 9m
Calculate the semi-perimeter (s) using
s = (5 + 6 + 9)/2
Evaluate
s = 10
The area is then calculated as:
![Area = \sqrt{s(s -a)(s-b)(s-c)](https://tex.z-dn.net/?f=Area%20%3D%20%5Csqrt%7Bs%28s%20-a%29%28s-b%29%28s-c%29)
This gives
![Area = \sqrt{10 * (10 -5)(10-6)(10-9)](https://tex.z-dn.net/?f=Area%20%3D%20%5Csqrt%7B10%20%2A%20%2810%20-5%29%2810-6%29%2810-9%29)
Evaluate the products
![Area = \sqrt{200](https://tex.z-dn.net/?f=Area%20%3D%20%5Csqrt%7B200)
Evaluate the exponent
Area = 14.1
Hence, the area of the triangle is 14.1 square meters
