Answer:
2A/h = b
Step-by-step explanation:
A= (1/2)(b)(h)
Multiply each side by 2
2A = 2*1/2 *b*h
2A = bh
Divide each side by h
2A/h = bh/h
2A/h = b
2(2) + 3(3) =
4 + 9 = 13
I don't know what 90p means but basically, u have to multiply that by 3 and add it to our current total which is 13.
Then, u substract the total cost from the 20 and you should get the change.
