Answer:

Look below

Step-by-step explanation:

(a) The area of a triangle is:

A=\frac{1}{2}bh

The height of this triangle is h and it's base is 4+h so...

A=\frac{1}{2}*[h*(h+4)]

A=\frac{1}{2}*(h^2+4h)\\A=\frac{h^2}{2}+2h

(b) If the height is 8 cm, then the base is 4+8 which is 12 cm so...

A=\frac{1}{2}*8*12=4*12=48 \ cm^2

Find the area of the figure.EXPlAIN THE STEPS!!!!
hichkok12 [17]

Answer:

30.56 yd²

Step-by-step explanation:

To determine the area of the composite shape, we need to:

  1. Divide the shape into two smaller "known" shapes (Refer to image).
  2. Determine the area of those "known" shapes.
  3. Add the area of the known shapes to obtain the area of the figure.

<u>Determining the area of shape 1 (Rectangle 1):</u>

⇒ Area of rectangle = Lenght × Breadth

⇒                               = 2.1 × 4.8

⇒                               = 10.08 yd²

<u>Determining the area of shape 2 (Rectangle 2):</u>

⇒ Area of rectangle = Lenght × Breadth

⇒                               = 6.4 × 3.2

⇒                               = 20.48 yd²

<u>Determining the area of the figure:</u>

⇒ Area of figure = Area of rectangle 1 + Area of rectangle 2

⇒                         = 10.08 + 20.48

⇒                         = 30.56 yd²
