Area of kite is equal to 1/2 the product of the lengths of the diagonals

so
A=1/2(AD)(BF)

BF=BG+GF=8+8=18
AD=AG+GD=7+13.5=20.5

A=1/2(20.5)(18)=(8)(20.5)=164

now minus the area of the square
area of square=side^2=(CE)^2=9^2=81

kite-square=164-81=83 square meters

GaryK [48]
<h3>Answer: 24 units</h3>

Work Shown:

volume of pyramid = (1/3)*(area of base)*(height)

232 = (1/3)*(29)*h

232 = (29/3)*h

232*3/29 = h

24 = h

h = 24

How could you find the perimeter of an isosceles right triangle if you (8) already know the area?
netineya [11]

The area of a triangle is given in terms of the side lengths (b, h) as

... A = (1/2)bh

If b=h, then we can find the side length as ...

... A = (1/2)b²

... b = √(2A) . . . . . multiply by 2 and take the square root

The hypotenuse (x) can be found from the Pythagorean theorem:

... x² = b² + h² = 2b²

... x = b√2

The perimeter is the sum of the side lengths, so is

... P = b + b + x = 2√(2A) + (√(2A))·√2

... P = (2+√2)·√(2A)
