Question

I REALLY NEED HELP
A rectangle has a diagonal of 15ft. The width of the triangle is 12ft. What is the area of the rectangle.

Answer 1

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

Answer 2

9514 1404 393

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
