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

2.3 cm

Explanation:

`\textsf{Area of a trapezium}=(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 (1)/(2)(3.8 + 6.1)x=11.385`

`\implies (1)/(2)(9.9)x=11.385`

`\implies 9.9x=22.77`

`\implies x=2.3`
