Question

PLEASE I NEED HELP

1.Trapezoid BEAR has a height of 8.5 centimeters and parallel bases that measure 6.5 centimeters and 11.5 centimeters. To the nearest square centimeter, find the area of the trapezoid. Area of trapezoid BEAR = a0 square centimeters

2. Regular pentagon PENTA has side lengths that are 9 meters long. To the nearest square meter, find the area of the pentagon.

Area of pentagon PENTA =
a0 square meters

Answer 1

The are the area should be 86

Answer 2

Answer: 1) 76.5 cm²

2) 35.07 m²

Explanation:

1) The area of a trapezoid is A = (B + b)h/2

A = (11.5+6.5).8.5/2 = 18 . 8.5/2 = 153/2 = 76.5 cm²

2) For the pentagon, as it is a regular pentagon, we can divide it into 2 shapes. A equilateral triangle and a square.

Area of the square = l² = 9² = 81 m²

Area of a equilateral trinagle = l²√3/4 = 9²√3/4 = 81√3/42 = 81 . 1.73/2 = 140.3/4 = 35.07 m²
