A garden is in the shape of an isosceles right triangle. The length of the hypotenuse is 24 feet. What is the area of the triang

liubo4ka [24]

Answer:

Area = 144 ft^2

Step-by-step explanation:

Remark

Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.

Equations

a^2 + a^2 = c^2

Area = (1/2) * a^2

Givens

c = 24

Solution

Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.

a^2 + a^2 = c^2 Combine

2a^2 = 24^2 Expand

2a^2 = 576 Divide by 2

2a^2/2= 576/2

a^2 = 288 You might just as well leave this. go to area

Area = 1/2 (288)

Answer: Area = 144 ft^2

sweet [91]

Answer:

The length of the diagonal is 11.879 units

Step-by-step explanation:

On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

$a^2+b^2=c^2$

where a and b are the sides, and c is the diagonal.

$\rightarrow8.4^2+8.4^2=c^2\\\rightarrow70.56+70.56=c^2\\\rightarrow c^2=141.12\\\rightarrow c\approx11.879$
