Answer:
108 ft²
Step-by-step explanation:
The length of the other side of the rectangle can be found using the Pythagorean theorem.
15² = 12² + x²
x = √(225 -144) = √81 = 9
So, the rectangle is 9 ft by 12 ft. Its area is the product of those dimensions:
A = bh
A = (12 ft)(9 ft)
A = 108 ft² . . . . area of the rectangle
The area is 180ft I think. You can do (15*12)/2 = 90. Since it’s two triangles you then do 90*2. I hope I am right
