Question

Find the perimeter of the figure. round all figures to the nearest hundredth Place

Answer 1

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Height of trapezoid = 4 ft

Length of longer side= 'a' = 13 ft

Length of shorter side = 'b' = 9 ft

Due to height of 4 meter there will be right angle triangle at the corners.

In right angled triangle:

`H^2=B^2+P^2\\\\H^2=4^2+2^2\\\\H^2=16+4\\\\H^2=20\\\\H=√(20)\\\\H=2√(5)\ ft`

Since it is isosceles trapezoid, then there two non parallel sides should be equal.

So, Perimeter of isosceles trapezoid is given by

`13+9+2√(5)+2√(5)\\\\=22+4√(5)\\\\=30.94\ ft`

Hence, option 'c' is correct.

Answer 2

C

Explanation:

The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30

C is the best solution.
