Answer:
273 m^2
Step-by-step explanation:
Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2
Therefore,
11 x 14 is 154
154/2 = 77 m^2
Then, we find the area of the square which is just Base x Heigh
14 x 14 is 196m^2
And finally, we just add the two
77 + 196 = 273 m^2
The reason it's not m^3 is because we're not dealing with a third dimensional figure.
Btw, ^ means to the power of.
