The Composite Figure Is Made Up Of A Triangle A Square And A Trapezoid Findthe Area class=

Sagot :

Answer:

The correct option is B

The area of the composite figure is 34.5 sq. units

Explanation:

The area of the composite figure is the sum of the areas of each shape.

That is:

Area of triangle + Area of square + Area of trapezoid

Area of triangle = 1/2 (base)(height)

= 1/2 (3)(2)

= 3

Area of square = l^2

= 3^2

= 9

Area of trapezoid = 5[4 + (3 + 1 + 1)]/2

= 5(9)/2

= 22.5

Area of figure = 3 + 9 + 22.5

= 34.5
