Pls help me I’m stuck

19.98 ft^2

Step-by-step explanation:

Area of a trapezium formula:

so, 1/2 multiplied by 3.7(4.3+6.5)= 19.98

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
