Answer: 5 to the 3rd times 3 to the second times 2
Step-by-step explanation:
It would be the third one
You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m
20x4=80
i am assuming this is correct this is how i learned just take all numbers in equation and multiply by each other
