Question

Can some please help me

Answer 1

Area of trapezoid 1/2(sum of parallel sides)(Height)

• 1/2(6.1+3.8)x=11.385
• 1/2(9.9)x=11.385
• 9.9x=22.77
• x=22.77/9.9
• x=2.3

Answer 2

Answer:

2.3 cm

Step-by-step explanation:

$\textsf{Area of a trapezium}=\dfrac{1}{2}(a+b)h \quad \textsf{(where a and b are the bases and h is the height)}$

Given:

• base a = 3.8 cm
• base b = 6.1 cm
• h = x cm

Substituting the given values into the formula and solving for x:

$\implies \dfrac{1}{2}(3.8 + 6.1)x=11.385$

$\implies \dfrac{1}{2}(9.9)x=11.385$

$\implies 9.9x=22.77$

$\implies x=2.3$
