Answer:
A = 14 m^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h where b is the length of the bases and h is the height
A = 1/2 (2+5) *4
A = 1/2(7)4
A = 14 m^2
<em>Answer:</em>
<em>n = 12</em>
<em>Step-by-step explanation:</em>
<em>85%×n = 10.2</em>
<em>85n/100 = 10.2</em>
<em>85n = 1020</em>
<em>n = 1020 : 85</em>
<em>n = 12</em>
Answer:

There are two best ways to solve this.
