PLEASE HELP! So for this problem I tried multiplying, adding, using square roots, however, my answers were all wrong. How do I solve this problem?

9514 1404 393

  384 square yards

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW . . . . . where L and W stand for Length and Width

Using the given dimensions, you find the area to be ...

  A = (24 yd)(16 yd) = 24×16 yd² = 384 yd²

The area of the figure is 384 square yards.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

y-3=-3/2(x+4)

ur very much welcome
