This trapezoid is composed of a rectangle and two triangles. what is the area of the trapezoid? a) 44cm2 b)40cm2 c)36cm2

A)

Step-by-step explanation:

Given:

Trapezoid is composed of 2 triangles and 1 rectangle.

In order to find area of trapezoid, we will find area of each shape contained in the trapezoid and add them together

Area of triangles:

Base = 2 cm

Height = 4 cm

Area of a triangle =

Plugging in given values.

Area of a triangle =

Ares of other triangle would be same as they have same height and base.

So, Area of two triangles =

Area of rectangle:

Length = 9 cm

Width = 4 cm

Area of rectangle  =

Area of rectangle  =

So, area of trapezoid =

∴ Area of trapezoid =

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
