Answer:
47
Step-by-step explanation:
The diagonals of a parallelogram bisect in their middle point, so :
2u + 9 = 5u - 48
3u = 57
u = 19
EI = 5* 19 - 48 = 47

=47.8888 when you round it up you can get get about 48 then you estimate to about 50.
Area = Length x Width
so, 88 = (something) x 8
Can you work out the something using mental math?
