Here's 9.
60 m - 32 m = 28 m. That's the base.
Area of a triangle is (Base x height) / 2.
28X28=784
784/2 = 392
But you have 2 traingles so you multiply by 2. So 392x2 = 784.

KiRa [710]

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

$\frac{L}{W}=\frac{5}{3}$

Where:

L represents the new length
W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

$L=18-x$

$W=12-x$

Then, we will have:

$\frac{18-x}{12-x}=\frac{5}{3}$

Finally, we just need to solve it for x.

$3(18-x)=5(12-x)$

$5x-3x=60-54$

$2x=6$

$x=3$

Therefore, the value of x = 3.

I hope it helps you!
