Answer 1

Answer:

height = 5 ft

Step-by-step explanation:

area of a trapezoid = $\dfrac12(a+b)h$

where a and b are the bases and h is the height

Given:

• area = 25.5 ft²
• base a = 3.2 ft
• base b = 7 ft

$\implies 25.5=\dfrac12(3.2+7)h\\\\\implies 25.5=5.1h\\\\\implies h=5$

Answer 2

Height be h

• Area =1/2(Sum of parallel sides)×height

$\\ \rm\hookrightarrow 1/2(3.2+7)h=25.5$

$\\ \rm\hookrightarrow 10.2h=51$

$\\ \rm\hookrightarrow h=5ft$
