Answer:
A=L x W or Area = Length x Width, Area: 6 units^2, Perimeter: 9 units
Step-by-step explanation:
The bottom of the triangle measures 3 but it's split in half. 3 divided by 2 is 1.5. The formula is L x W so multiply 4 x 1.5.
To find the perimeter you just add the outer measures. if the bottom of the triangle is 3 and the top right is 3 then the top left must be 3. To find perimeter you add them and 3+3+3=9
Hope this helped :)
