The triangle is 28 cm. You multiple 7 x 8x 1/2.
the parallelogram is 50. the formula is A=bh ( area = base x height)
In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)
So far he has 63+72+88+91= 314
400-314=86
He needs to get 86 points from the last test.
Since he is obviously getting better at tests, i think he'll manage :)
