Answer:

The plot is made up of a rectangle and a trapezium:

Total area = area of rectangle+area of trapezium

{ \tt{area =  2(l + w) +  \frac{1}{2} h(a + b)}}

substitute:

{ \tt{area = 2 (300 + 196) +  \frac{1}{2} (300 - 196)(480 + 300) }} \\  \\ { \tt{area = 992 + 40560}} \\  \\ { \boxed{ \boxed{ \tt{ \:  \: area = 41552 \:  \:  {m}^{2}  \:  \: }}}}

sattari [20]
Here is the answer. Given <span>3(2x−6) 3(2x−6), what we need to do is multiply 3 by 2x and -6 and this will give us this result. 6x-18 6x-18. Therefore, the answer for this is the first option. The expression that </span>shows the result of applying the distributive property to 3(2x−6)3(2x−6) is 6x-18 6x-18.

Area of triangle with points (7,7) (10,3) (7,3)
adelina 88 [10]

Answer:

The area of the triangle is of 6 units squared.

Step-by-step explanation:

Representation of the triangle:

This triangle, in the cartesian plane, has the vertices at these following points.

(7,7)

| -> 4 units down

(7,3) --- (10,3) -> 3 units to the right.

This can be represented as a right triangle with sides 4 and 3.

Area of a right triangle:

The area of a right triangle is the multiplication of the lengths of its sides divided by 2. So

4*3/2 = 12/2 = 6.

The area of the triangle is of 6 units squared.
