Answer 1

Answer:

398 ft²

Step-by-step explanation:

Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.

Triangle area = 1/2·bh

Rectangle area = bh

___

So, the first triangle has an area of ...

1/2·(20 ft)(20 ft) = 200 ft²

The second triangle has an area of ...

1/2·(6 ft)(6 ft) = 18 ft²

The rectangle has an area of ...

(30 ft)(6 ft) = 180 ft²

And the area total is ...

200 ft² +18 ft² +180 ft² = 398 ft²

Answer 2

Answer:

220.5 sq feet

Step-by-step explanation:

Given : Bev has to cut her grandma's grass this weekend

Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.

To Find : Area of Polygon

Solution:

Area of triangle = (1/2) bh

= (1/2) * 15 * 15

= 112.5   sq feet

= (1/2) * 4 * 4

=  8   sq feet

Area of rectangle = 25 x 4 = 100   sq feet

Total area =112.5 +  8  + 100

= 220.5 sq feet

Area of Polygon = 220.5 sq feet
