Answer:

The area of the triangle is 21 ft (640.08 centimeters)

The area of the rectangle is 120 ft (3657.6 centimeters)

The area of the whole figure is 141 ft (4297.68 centimeters)

Explanation:

The area of a triangle is:


A = (1)/(2)bh b is the base and h is the height.

Plug in what you have


A= (1)/(2)(6)(7) multiply 6 by 7


A = (1)/(2) (42) divide 42 by 2


A = (42)/(2)


A = 21

Now you have to find the area of the rectangle

The area of a rectangle is:

A = bh

Plug in what you have

A = (10)(12)

A = 120

Now add both areas together to get the area of the whole figure

120 + 21 = 141

Answer:

21 sq ft

Explanation:

The formula is 0.5bh; b is the length of the base (6) and h is the height (7). So if you plug in those values, you have 0.5(6)(7). Multiply those and you get 21!
