Answer 1

Explanation:

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

Six-sided polygon that includes two isosceles right triangles, one with height and base of 20 feet, the other height and base of 6 feet, and one rectangle measuring 30 feet by 6 feet.

To Find : Area of Polygon

Solution:

Area of triangle = (1/2) bh

= (1/2) * 20 * 20

= 200 sq feet

= (1/2) * 6 * 6

= 18 sq feet

Area of rectangle = 30 x 6 = 180 sq feet

Total area = 200 + 18 + 180

= 398 sq feet

Area of Polygon = 398 sq feet
