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 =

i think 5 miles per hour
