Answer:
The answer is 102 cm²
Explanation:
Data
EL = 6.0 cm
KE = 8.5 cm
Formula
area = (d1) ( d2)/2
where :
d₁ is the length of a diagonal
d₂ is the length of the other diagonal
So we need to multiply each data by two because we only have half of the length needed.
Then:
d₁ = 6.0 x 2 = 12 cm
d₂ = 8.5 x 2 = 17 cm
Finally, we substitute the values in the formula
area = (12)(17)/2 = 102 cm²
