A pentagon is made of a triangle and a trapezoid. The height of the triangle shown is about 541 feet, and the height of the trapezoid is about 876 feet. Estimate the land area of the Pentagon.

  about 1,459,063 ft^2

Step-by-step explanation:

The area of the triangle is ...

  A = (1/2)bh = (1/2)(1490 ft)(541 ft) = 403045 ft^2

The area of the trapezoid is ...

  A = (1/2)(b1 +b2)h = (1/2)(1490 ft +921 ft)(876 ft) = 1056018 ft^2

Then the total land area is about ...

  403,045 ft^2 +1,045,018 ft^2 = 1,459,063 ft^2

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
