Step-by-step explanation:
"If the sum of 2 angles is 180°, then each is the supplementary angle of the other".
Let the length of the rectangle is x. units , accordingly :
2.(x+3) = x×3.
2x + 6 = 3x.
x = 6 units is the answer :)
U just need to add all the numbers together
24 x 0.25
6
24+6
30
so the answer is £30
