Answer:
24 units
Step-by-step explanation:
80 / 5 = 16
16 x 3 = 48
48 = length
16 = width
divide by 2
24 = length
8 = width
you divide by 5 because there will be 5 parts if the breadth/width was 1 part so you can find out the length by multipling by 4.
you dont know the width so you divide the perimeter by 5 and then divide the answer you got by 2 because there is 2 of each on a rectangle
EDIT: its a triangle sorry this wont help
