Answer:
34.04 cm²
Step-by-step explanation:
Formula for a trapezoid:
a + b ÷ 2 × height
Substitute the values:
11.7 + 3.1 = 14.8
14.8 ÷ 2 = 7.4
7.4 × 4.6 = 34.04
The answer is 34.04 cm²
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
