Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
