Answer:
The area of the triangle is 144.5cm
Step-by-step explanation:
You start with a 34cm by 17cm rectangle. It shows the amount of empty space on each side of the length of the triangle, so you start by subtracting those two numbers (7 and 10) from 34.
34-10-7=17
Next multiply the length of the triangle (17) by the width of the triangle (17)
17*17=289
Now to find the area of the triangle divide 289 in half because the number you have is representing the area of a full square and you only need half of that because it's a triangle.
289/2=144.5
You got this and I hope you have a wonderful day! Make sure to take breaks whenever you get stressed so you don't overwhelm yourself :)
(maybe try making some tea or going on a walk to clear your head and sort of relax if you can)
