A garden in the shape of a trapezoid has an area of 44.4 square

Leviafan [203]

Answer:

37 meters

Step-by-step explanation:

The equation for the area of a trapezoid is $A=\frac{a+b}{2} +h$ .

Here, $a = 4.3$ , $b=10.5$ , and $h$ is unknown.

$44.4=\frac{4.3+10.5}{2} +h$

$44.4=\frac{14.8}{2} +h$

$44.4=7.4 +h$

$37 = h$

The height of the trapezoid is the width of the garden, so the garden is 37 meters wide.
