area = 25.5 cm²
Step-by-step explanation:
i have shown in the image you have to rotate it to see how i worked the area out
i am very sorry i cant work the perimeter out since i have no idea what the length of the two sides of the triangle are . if you need help on understanding how i worked out the area please let me know .
hopefully i was able to help you in half of the question i am sorry for not helping on the perimeter :)
