Question

What is the area of the triangle in this coordinate plane?​

Answer 1

Last option is correct answer.

The area of triangle = 49 square units

Explanation:

Formula:-

Area of triangle

Area A = bh/2

b - Base of triangle

h - Height of triangle

It is given a right angled triangle.

To find the base and height of triangle

From the figure we get the base of triangle, b = 7 units

Height of triangle, h = 15 - 1 = 14 units

To find the area of triangle

b = 7 units. h = 14 units

A = bh/2 = (7 * 14)/2 = 49 square units.

Therefore the area of triangle = 49 square units

Answer 2

`49.0\:units^2`

Explanation:

The area of a triangle can be found using the formula;

`Area=(1)/(2)bh`

Observe that each box is 1 unit.

This implies that;

`h=|15-1|=14\: units` is the height of the triangle.

`b=|7-0|=7\: units` is the base of the triangle.

We plug these values into the formula to get;

`Area=(1)/(2)(7)(14)`

`Area=7*7`

The area is
`49.0\:units^2`
