Question

Can someone please help me out ASAP I WILL GIVE OUT BRAINLY

Answer 1

Answer:

x=9

Perimeter:76 ft

Area:342 ft^2

Step-by-step explanation:

x:

8x-54=18

Then solve for x.

Perimeter: add all sides

(2(9)+1)+(2(9)+1)+18+18

Area: multiply length and width

18 x 19 = 342

Answer 2

Answer:

x = 9

Perimeter = 74

Area = 342

Step-by-step explanation:

First, find x. to do so, set your formula up as

18 = 8x - 54

18 + 54 = 8x

72 = 8x

72/8 = x

9 = x

Now that you have x, find your missing side

2x + 1 = y, x

2 * 9 + = y

19 = y

Your perimeter is P = 2(l+W)

P = 2(18 * 19)

P = 74

Your area is A = wl

A = 19 * 18

A = 342
