3cm
4cm
7cm
6cm

Answer 1

Answer: the area of the shape=25.5 cm²

Explanation:

This shape is composed of a rectangle and a trapezoid

The area of the rectangle= 3(4)

The area of the rectangle= 12 cm²

`\displaystyle\\The\ area\ of\ the\ trapezoid=(3+6)/(2) (7-4)\\\\The\ area\ of\ the\ trapezoid=(9)/(2) (3)\\\\The\ area\ of\ the\ trapezoid=4.5(3)\\\\The\ area\ of\ the\ trapezoid=13.5 \ cm^2`

The area of the shape=12+13.5

The area of the shape=25.5 cm²
