A rectangle has a length that is 9 feet less than four times its width. Its area is 90 square feet

kramer

Answer:

The length of rectangle is $15\ ft$

The width of rectangle is $6\ ft$

Step-by-step explanation:

Let

x-----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

$A=xy$

$A=90\ ft^{2}$

$90=xy$ -----> equation A

$x=4y-9$ -----> equation B

substitute equation B in equation A and solve for y

$90=(4y-9)y$

$4y^{2}-9y-90=0$

using a graphing calculator

The solution is

$y=6\ ft$

Find the value of x

$x=4y-9$ -----> $x=4(6)-9=15\ ft$

saveliy_v [14]

Move x
5y = - 15 - 3x
y = - 3 - 3/5x
y = - 3/5 - 3
-y = 3/5 + 3

Neporo4naja [7]

Answer:

41.7m²

Step-by-step explanation:

As we can see, the area of this shape is simply the sum of 3 rectangles

Rectangle A has an area of 6 times 4 or 24m²

Rectangle B has an area of (3.8-2) times 3.5 or 1.8 times 3.5 or 6.3m²

Rectangle C has an area of 3 times 3.8 or 11.4m²

Adding that up gives 41.7m²
