Question

Estimate the perimeter and area of the figure to the nearest whole number. Please help!!

Answer 1

Answer:

29 ; 37

Step-by-step explanation:

The figure is composed by a square, a rectangle, and a right triangle

The perimeter of the square is 6 units

The perimeter of the rectangle is 10 units

The triangle is composed by a side of 6 units and a side of 5 units

The third side can be find with the Pythagorean theorem

$\sqrt{6^2 + 5^2} = \sqrt{36 + 25} = \sqrt{61}$ = 7,81025

The total perimeter is

6 + 10 + 5 + 7,81025 = 28,81025 = 29

Area of the square = 2^2 = 4 square units

Area of the rectangle = 6 x 3 = 18 square units

Area of the triangle =  (5 x 6)/2 = 15 square units

Total area = 4 + 18 + 15 = 37 square units

Answer 2

Answer:

29; 37

Step-by-step explanation:

The figure is composed by a square, a rectangle, and a right triangle

The perimeter of the square is 6 units

The perimeter of the rectangle is 10 units

The triangle is composed by a side of 6 units and a side of 5 units

The third side can be find with the Pythagorean theorem √62 +52 √36 + 25 = √61 = 7,81025 = +25

The total perimeter is

6+10+5+7,81025 = 28,81025 = 29

Area of the square = 2^2 = 4 square units Area of the rectangle = 6 x 3 = 18 square units Area of the triangle = (5 x 6)/2 = 15 square units

Total area = 4 + 18 + 15 = 37 square units
