Question

PLEASEEEEEEEEEEEE *cries*

Answer 1

Answer:

D) a: 4(4) + 1/2(3)(4)

Step-by-step explanation:

1. The floor is split into a square and a triangle, as the two side lengths of the quadrilateral are both 4 feet.

C and D are looking for the area of a rectangle and a triangle. They can not be right.

2. The area of a triangle is found by multiplying the base and the height, which in this case, since it is a right triangle, the two legs. In that situation, said legs are 7 - 4 = 3 feet and 4 feet, while the hypotenuse is 5 ft. B plugs in the equation leg * hypotenuse, which is not correct.

The only answer is A (which is D in the selection).
